Exhibit 10.4

CARGURUS, INC.

OMNIBUS INCENTIVE COMPENSATION PLAN

Effective as of the Effective Date (as defined below), the CarGurus, Inc. Omnibus Incentive Compensation Plan (the “Plan”) is hereby established as a successor to the CarGurus, Inc. Amended and Restated 2015 Equity Incentive Plan (the “Prior Plan”). No additional grants shall be made under the Prior Plan on and after the Effective Date. Outstanding grants under the Prior Plan shall continue in effect according to their terms, and the shares with respect to outstanding grants under the Prior Plan shall be issued or transferred under the Prior Plan.

The purpose of the Plan is to provide employees of CarGurus, Inc. (the “Company”) and its subsidiaries, certain consultants and advisors who perform services for the Company or its subsidiaries, and non-employee members of the Board of Directors of the Company with the opportunity to receive grants of incentive stock options, nonqualified stock options, stock appreciation rights, stock awards, stock units, other stock-based awards and cash awards.

The Company believes that the Plan will encourage the participants to contribute materially to the growth of the Company, thereby benefitting the Company’s stockholders, and will align the economic interests of the participants with those of the stockholders.

(ii) The consummation of (A) a merger or consolidation of the Company with another corporation where, immediately after the merger or consolidation, the stockholders of the Company, immediately prior to the merger or consolidation, will not beneficially own, in substantially the same proportion as ownership immediately prior to the merger or consolidation, shares entitling such stockholders to more than 50% of all votes to which all stockholders of the surviving corporation would be entitled in the election of directors, or where the members of the Board, immediately prior to the merger or consolidation, will not, immediately after the merger or consolidation, constitute a majority of the board of directors of the surviving corporation or (B) a sale or other disposition of all or substantially all of the assets of the Company.

To the extent that the Board, the Committee, a subcommittee or the CEO, as described below, administers the Plan, references in the Plan to the “Committee” shall be deemed to refer to the Board, the Committee, such subcommittee or the CEO.

Subject to compliance with applicable law and applicable stock exchange requirements, the Committee may delegate all or part of its authority and power to the CEO, as it deems appropriate, with respect to Grants to Employees or Key Advisors who are not executive officers or directors under section 16 of the Exchange Act.

(c) Committee Authority. The Committee shall have the sole authority to (i) determine the individuals to whom Grants shall be made under the Plan, (ii) determine the type, size, terms and conditions of the Grants to be made to each such individual, (iii) determine the time when the Grants will be made and the duration of any applicable exercise or restriction period, including the criteria for exercisability and the acceleration of exercisability, (v) amend the terms of any previously issued Grant, subject to the provisions of Section 18 below, and (vi) deal with any other matters arising under the Plan.

(d) Committee Determinations.

The Committee’s interpretations of the Plan and all determinations made by the Committee pursuant to the powers vested in it hereunder shall be conclusive and binding on all persons having any interest in the Plan or in any awards granted hereunder. All powers of the Committee shall be executed in its sole discretion, in the best interest of the Company, not as a fiduciary, and in keeping with the objectives of the Plan and need not be uniform as to similarly situated individuals.

(e) Indemnification. No member of the Committee or the Board, and no employee of the Company shall be liable for any act or failure to act with respect to the Plan, except in circumstances involving his or her bad faith or willful misconduct, or for any act or failure to act hereunder by any other member of the Committee or employee or by any agent to whom duties in connection with the administration of this Plan have been delegated. The Company shall indemnify members of the Committee and the Board and any agent of the Committee or the Board who is an employee of the Company or a subsidiary against any and all liabilities or expenses to which they may be subjected by reason of any act or failure to act with respect to their duties on behalf of the Plan, to the fullest extent permissible under applicable law and in accordance with any applicable agreements with the Company.

All Grants shall be made conditional upon the Participant’s acknowledgement, in writing or by acceptance of the Grant, that all decisions and determinations of the Committee shall be final and binding on the

6

Participant, his or her beneficiaries and any other person having or claiming an interest under such Grant. Grants under a particular Section of the Plan need not be uniform as among the Participants.

Section 4. Shares Subject to the Plan

(a) Shares Authorized. Subject to adjustment as described below in Section 4(d), the aggregate number of shares of Company Stock that may be issued or transferred under the Plan shall be equal to the sum of the following: (i) 7,800,000 shares of Company Stock, plus (ii) the number of shares of Company Stock (up to 4,500,000 shares) equal to the sum of (x) the number of shares of Company Stock and Class B Common Stock of the Company subject to outstanding grants under the Prior Plan as of the Effective Date that terminate, expire or are cancelled, forfeited, exchanged or surrendered on or after the Effective Date without having been exercised, vested or paid prior to the Effective Date, including shares tendered or withheld to satisfy tax withholding obligations with respect to outstanding grants under the Prior Plan, plus (y) the number of shares of Company Stock reserved for issuance under the Prior Plan that remain available for grant under the Prior Plan as of the Effective Date. The aggregate number of shares of Company Stock that may be issued or transferred under the Plan pursuant to Incentive Stock Options shall not exceed 12,300,000 shares of Company Stock. In addition, as of the first trading day of January during the term of the Plan (excluding any extensions), beginning with calendar year 2019, an additional positive number of shares of Company Stock shall be added to the number of shares of Company Stock authorized to be issued or transferred under the Plan and the number of shares authorized to be issued or transferred pursuant to Incentive Stock Options, equal to 4% of the total number of shares of Company Stock outstanding on the last trading day in December of the immediately preceding calendar year or 6,000,000 shares, whichever is less, or such lesser amount as determined by the Board.

(b) Source of Shares; Share Counting. Shares issued or transferred under the Plan may be authorized but unissued shares of Company Stock or reacquired shares of Company Stock, including shares purchased by the Company on the open market for purposes of the Plan. If and to the extent Options or SARs granted under the Plan (including options granted under the Prior Plan) terminate, expire or are canceled, forfeited, exchanged or surrendered without having been exercised, or if any Stock Awards, Stock Units or Other Stock-Based Awards (including stock units granted under the Prior Plan) are forfeited, terminated or otherwise not paid in full, the shares subject to such Grants shall again be available for purposes of the Plan. If shares of Company Stock otherwise issuable under the Plan are surrendered in payment of the Exercise Price of an Option, then the number of shares of Company Stock available for issuance under the Plan shall be reduced only by the net number of shares actually issued by the Company upon such exercise and not by the gross number of shares as to which such Option is exercised. Upon the exercise of any SAR under the Plan, the number of shares of Company Stock available for issuance under the Plan shall be reduced by only by the net number of shares actually issued by the Company upon such exercise. If shares of Company Stock otherwise issuable under the Plan are withheld by the Company in satisfaction of the withholding taxes incurred in connection with the issuance, vesting or exercise of any Grant or the issuance of Company Stock thereunder, then the number of shares of Company Stock available for issuance under the Plan shall be reduced

7

by the net number of shares issued, vested or exercised under such Grant, calculated in each instance after payment of such share withholding. To the extent any Grants are paid in cash, and not in shares of Company Stock, any shares previously subject to such Grants shall again be available for issuance or transfer under the Plan.

(c) Substitute Awards. Shares issued or transferred under Grants made pursuant to an assumption, substitution or exchange for previously granted awards of a company acquired by the Company in a transaction (“Substitute Awards”) shall not reduce the number of shares of Company Stock available under the Plan and available shares under a stockholder approved plan of an acquired company (as appropriately adjusted to reflect the transaction) may be used for Grants under the Plan and shall not reduce the Plan’s share reserve (subject to applicable stock exchange listing and Code requirements).

(d) Adjustments. If there is any change in the number or kind of shares of Company Stock outstanding by reason of (i) a stock dividend, spinoff, recapitalization, stock split, or combination or exchange of shares, (ii) a merger, reorganization or consolidation, (iii) a reclassification or change in par value, or (iv) any other extraordinary or unusual event affecting the outstanding Company Stock as a class without the Company’s receipt of consideration, or if the value of outstanding shares of Company Stock is substantially reduced as a result of a spinoff or the Company’s payment of an extraordinary dividend or distribution, the maximum number and kind of shares of Company Stock available for issuance under the Plan, the kind and number of shares covered by outstanding Grants, the kind and number of shares issued and to be issued under the Plan, and the price per share or the applicable market value of such Grants shall be equitably adjusted by the Committee to reflect any increase or decrease in the number of, or change in the kind or value of, the issued shares of Company Stock to preclude, to the extent practicable, the enlargement or dilution of rights and benefits under the Plan and such outstanding Grants; provided, however, that any fractional shares resulting from such adjustment shall be eliminated. In addition, in the event of a Change of Control, the provisions of Section 13 of the Plan shall apply. Any adjustments to outstanding Grants shall be consistent with section 409A or 424 of the Code, to the extent applicable. The adjustments of Grants under this Section 4(d) shall include adjustment of shares, Exercise Price of Stock Options, base amount of SARs, performance goals or other terms and conditions, as the Committee deems appropriate. The Committee shall have the sole discretion and authority to determine what appropriate adjustments shall be made and any adjustments determined by the Committee shall be final, binding and conclusive.

Section 5. Eligibility for Participation

(a) Eligible Persons. All Employees and Non-Employee Directors shall be eligible to participate in the Plan. Key Advisors shall be eligible to participate in the Plan if the Key Advisors render bona fide services to the Employer, the services are not in connection with the offer and sale of securities in a capital-raising transaction and the Key Advisors do not directly or indirectly promote or maintain a market for the Company’s securities.

8

(b) Selection of Participants. The Committee shall select the Employees, Non-Employee Directors and Key Advisors to receive Grants and shall determine the number of shares of Company Stock subject to a particular Grant in such manner as the Committee determines.

Section 6. Options

The Committee may grant Options to an Employee, Non-Employee Director or Key Advisor upon such terms as the Committee deems appropriate. The following provisions are applicable to Options:

(a) Number of Shares. The Committee shall determine the number of shares of Company Stock that will be subject to each Grant of Options to Employees, Non-Employee Directors and Key Advisors.

(b) Type of Option and Exercise Price.

(i) The Committee may grant Incentive Stock Options or Nonqualified Stock Options or any combination of the two, all in accordance with the terms and conditions set forth herein. Incentive Stock Options may be granted only to employees of the Company or its parent or subsidiary corporations, as defined in section 424 of the Code. Nonqualified Stock Options may be granted to Employees, Non-Employee Directors and Key Advisors.

(ii) The Exercise Price of Company Stock subject to an Option shall be determined by the Committee and shall be equal to or greater than the Fair Market Value of a share of Company Stock on the date the Option is granted. However, an Incentive Stock Option may not be granted to an Employee who, at the time of grant, owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, or any parent or subsidiary corporation of the Company, as defined in section 424 of the Code, unless the Exercise Price per share is not less than 110% of the Fair Market Value of a share of Company Stock on the date of grant.

(c) Option Term. The Committee shall determine the term of each Option. The term of any Option shall not exceed ten years from the date of grant. However, an Incentive Stock Option that is granted to an Employee who, at the time of grant, owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, or any parent or subsidiary corporation of the Company, as defined in section 424 of the Code, may not have a term that exceeds five years from the date of grant. Notwithstanding the foregoing, in the event that on the last business day of the term of an Option (other than an Incentive Stock Option), the exercise of the Option is prohibited by applicable law, including a prohibition on purchases or sales of Company Stock under the Company’s insider trading policy, the term of the Option shall be extended for a period of 30 days following the end of the legal prohibition, unless the Committee determines otherwise.

9

(d) Exercisability of Options. Options shall become exercisable in accordance with such terms and conditions, consistent with the Plan, as may be determined by the Committee and specified in the Grant Instrument. The Committee may accelerate the exercisability of any or all outstanding Options at any time for any reason.

(e) Grants to Non-Exempt Employees. Notwithstanding the foregoing, Options granted to persons who are non-exempt employees under the Fair Labor Standards Act of 1938, as amended, may not be exercisable for at least six months after the date of grant (except that such Options may become exercisable, as determined by the Committee, upon the Participant’s death, Disability or retirement, or upon a Change of Control or other circumstances permitted by applicable regulations).

(f) Termination of Employment or Service. Except as provided in the Grant Instrument, an Option may only be exercised while the Participant is employed by, or providing services to, the Employer. The Committee shall determine in the Grant Instrument under what circumstances and during what time periods a Participant may exercise an Option after termination of employment or service.

(g) Exercise of Options. A Participant may exercise an Option that has become exercisable, in whole or in part, by delivering a notice of exercise to the Company or its delegate. The Participant shall pay the Exercise Price for an Option as specified by the Committee (i) in cash, (ii) unless the Committee determines otherwise, by delivering shares of Company Stock owned by the Participant and having a Fair Market Value on the date of exercise at least equal to the Exercise Price or by attestation (in accordance with procedures prescribed by the Company) to ownership of shares of Company Stock having a Fair Market Value on the date of exercise at least equal to the Exercise Price, (iii) by payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board, or (iv) by such other method as the Committee may approve. In addition, to the extent an Option is at the time exercisable for vested shares of Company Stock, all or any part of that vested portion may be surrendered to the Company for an appreciation distribution payable in shares of Company Stock with a Fair Market Value at the time of the Option surrender equal to the dollar amount by which the then Fair Market Value of the shares of Company Stock subject to the surrendered portion exceeds the aggregate Exercise Price payable for those shares (“net exercise”). Shares of Company Stock used to exercise an Option shall have been held by the Participant for the requisite period of time necessary to avoid adverse accounting consequences to the Company with respect to the Option. Payment for the shares to be issued or transferred pursuant to the Option, and any required withholding taxes, must be received by the Company by the time specified by the Committee depending on the type of payment being made, but in all cases prior to the issuance or transfer of such shares.

(h) Limits on Incentive Stock Options. Each Incentive Stock Option shall provide that, if the aggregate Fair Market Value of the Company Stock on the date of the grant with respect to which Incentive Stock Options are exercisable for the first time by a Participant during any calendar year, under the Plan or any other stock option plan of the Company or a

10

parent or subsidiary, exceeds $100,000, then the Option, as to the excess, shall be treated as a Nonqualified Stock Option.

Section 7. Stock Awards

The Committee may issue or transfer shares of Company Stock to an Employee, Non-Employee Director or Key Advisor under a Stock Award, upon such terms as the Committee deems appropriate. The following provisions are applicable to Stock Awards:

(a) General Requirements. Shares of Company Stock issued or transferred pursuant to Stock Awards may be issued or transferred for consideration or for no consideration, and subject to restrictions or no restrictions, as determined by the Committee. The Committee may, but shall not be required to, establish conditions under which restrictions on Stock Awards shall lapse over a period of time or according to such other criteria as the Committee deems appropriate, including, without limitation, restrictions based upon the achievement of specific performance goals. The period of time during which the Stock Awards will remain subject to restrictions will be designated in the Grant Instrument as the “Restriction Period.”

(b) Number of Shares. The Committee shall determine the number of shares of Company Stock to be issued or transferred pursuant to a Stock Award and the restrictions applicable to such shares.

(c) Requirement of Employment or Service. If the Participant ceases to be employed by, or provide service to, the Employer during a period designated in the Grant Instrument as the Restriction Period, or if other specified conditions are not met, the Stock Award shall terminate as to all shares covered by the Grant as to which the restrictions have not lapsed, and those shares of Company Stock must be immediately returned to the Company. The Committee may, however, provide for complete or partial exceptions to this requirement as it deems appropriate.

(d) Restrictions on Transfer and Legend on Stock Certificate. During the Restriction Period, a Participant may not sell, assign, transfer, pledge or otherwise dispose of the shares of a Stock Award except under Section 16 below. Unless otherwise determined by the Committee, the Company will retain possession of certificates for shares of Stock Awards until all restrictions on such shares have lapsed. Each certificate for a Stock Award, unless held by the Company, shall contain a legend giving appropriate notice of the restrictions in the Grant. The Participant shall be entitled to have the legend removed from the stock certificate covering the shares subject to restrictions when all restrictions on such shares have lapsed. The Committee may determine that the Company will not issue certificates for Stock Awards until all restrictions on such shares have lapsed.

(e) Right to Vote and to Receive Dividends. Unless the Committee determines otherwise, during the Restriction Period, the Participant shall have the right to vote shares of Stock Awards and to receive any dividends or other distributions paid on such shares, subject to any restrictions deemed appropriate by the Committee, including, without limitation, the achievement of specific performance goals. Dividends with respect to Stock Awards that vest

11

based on performance shall vest if and to the extent that the underlying Stock Award vests, as determined by the Committee.

(f) Lapse of Restrictions. All restrictions imposed on Stock Awards shall lapse upon the expiration of the applicable Restriction Period and the satisfaction of all conditions, if any, imposed by the Committee. The Committee may determine, as to any or all Stock Awards, that the restrictions shall lapse without regard to any Restriction Period.

Section 8. Stock Units

The Committee may grant Stock Units, each of which shall represent one hypothetical share of Company Stock, to an Employee, Non-Employee Director or Key Advisor upon such terms and conditions as the Committee deems appropriate. The following provisions are applicable to Stock Units:

(a) Crediting of Units. Each Stock Unit shall represent the right of the Participant to receive a share of Company Stock or an amount of cash based on the value of a share of Company Stock, if and when specified conditions are met. All Stock Units shall be credited to bookkeeping accounts established on the Company’s records for purposes of the Plan.

(b) Terms of Stock Units. The Committee may grant Stock Units that vest and are payable if specified performance goals or other conditions are met, or under other circumstances. Stock Units may be paid at the end of a specified performance period or other period, or payment may be deferred to a date authorized by the Committee. The Committee may accelerate vesting or payment, as to any or all Stock Units at any time for any reason, provided such acceleration complies with section 409A of the Code. The Committee shall determine the number of Stock Units to be granted and the requirements applicable to such Stock Units.

(c) Requirement of Employment or Service. If the Participant ceases to be employed by, or provide service to, the Employer prior to the vesting of Stock Units, or if other conditions established by the Committee are not met, the Participant’s Stock Units shall be forfeited. The Committee may, however, provide for complete or partial exceptions to this requirement as it deems appropriate.

(d) Payment With Respect to Stock Units. Payments with respect to Stock Units shall be made in cash, Company Stock or any combination of the foregoing, as the Committee shall determine.

Section 9. Stock Appreciation Rights

The Committee may grant SARs to an Employee, Non-Employee Director or Key Advisor separately or in tandem with any Option. The following provisions are applicable to SARs:

(a) General Requirements. The Committee may grant SARs to an Employee, Non-Employee Director or Key Advisor separately or in tandem with any Option (for all or a

12

portion of the applicable Option). Tandem SARs may be granted either at the time the Option is granted or at any time thereafter while the Option remains outstanding; provided, however, that, in the case of an Incentive Stock Option, SARs may be granted only at the time of the grant of the Incentive Stock Option. The Committee shall establish the base amount of the SAR at the time the SAR is granted. The base amount of each SAR shall be equal to or greater than the Fair Market Value of a share of Company Stock as of the date of grant of the SAR. The term of any SAR shall not exceed ten years from the date of grant. Notwithstanding the foregoing, in the event that on the last business day of the term of a SAR, the exercise of the SAR is prohibited by applicable law, including a prohibition on purchases or sales of Company Stock under the Company’s insider trading policy, the term shall be extended for a period of 30 days following the end of the legal prohibition, unless the Committee determines otherwise.

(b) Tandem SARs. In the case of tandem SARs, the number of SARs granted to a Participant that shall be exercisable during a specified period shall not exceed the number of shares of Company Stock that the Participant may purchase upon the exercise of the related Option during such period. Upon the exercise of an Option, the SARs relating to the Company Stock covered by such Option shall terminate. Upon the exercise of SARs, the related Option shall terminate to the extent of an equal number of shares of Company Stock.

(c) Exercisability. An SAR shall be exercisable during the period specified by the Committee in the Grant Instrument and shall be subject to such vesting and other restrictions as may be specified in the Grant Instrument. The Committee may accelerate the exercisability of any or all outstanding SARs at any time for any reason. SARs may only be exercised while the Participant is employed by, or providing service to, the Employer or during the applicable period after termination of employment or service as specified by the Committee. A tandem SAR shall be exercisable only during the period when the Option to which it is related is also exercisable.

(d) Grants to Non-Exempt Employees. Notwithstanding the foregoing, SARs granted to persons who are non-exempt employees under the Fair Labor Standards Act of 1938, as amended, may not be exercisable for at least six months after the date of grant (except that such SARs may become exercisable, as determined by the Committee, upon the Participant’s death, Disability or retirement, or upon a Change of Control or other circumstances permitted by applicable regulations).

(e) Value of SARs. When a Participant exercises SARs, the Participant shall receive in settlement of such SARs an amount equal to the value of the stock appreciation for the number of SARs exercised. The stock appreciation for an SAR is the amount by which the Fair Market Value of the underlying Company Stock on the date of exercise of the SAR exceeds the base amount of the SAR as described in subsection (a).

(f) Form of Payment. The appreciation in an SAR shall be paid in shares of Company Stock, cash or any combination of the foregoing, as the Committee shall determine. For purposes of calculating the number of shares of Company Stock to be received, shares of Company Stock shall be valued at their Fair Market Value on the date of exercise of the SAR.

13

Section 10. Other Stock-Based Awards

The Committee may grant Other Stock-Based Awards, which are awards (other than those described in Sections 6, 7, 8 and 9 of the Plan) that are based on or measured by Company Stock, to any Employee, Non-Employee Director or Key Advisor, on such terms and conditions as the Committee shall determine. Other Stock-Based Awards may be awarded subject to the achievement of performance goals or other conditions and may be payable in cash, Company Stock or any combination of the foregoing, as the Committee shall determine.

Section 11. Cash Awards

The Committee may grant Cash Awards to Employees who are executive officers and other key employees of the Company. The Committee shall determine the terms and conditions applicable to Cash Awards, including the criteria for the vesting and payment of Cash Awards. Cash Awards shall be based on such measures as the Committee deems appropriate and need not relate to the value of shares of Company Stock.

Section 12. Dividend Equivalents

The Committee may grant Dividend Equivalents in connection with Stock Units or Other Stock-Based Awards. Dividend Equivalents may be paid currently or accrued as contingent cash obligations and may be payable in cash or shares of Company Stock, and upon such terms and conditions as the Committee shall determine. Dividend Equivalents with respect to Stock Units or Other Stock-Based Awards that vest based on performance shall vest and be paid only if and to the extent the underlying Stock Units or Other Stock-Based Awards vest and are paid, as determined by the Committee.

Section 13. Consequences of a Change of Control

(a) Assumption of Outstanding Grants. Upon a Change of Control where the Company is not the surviving corporation (or survives only as a subsidiary of another corporation), unless the Committee determines otherwise, all outstanding Grants that are not exercised or paid at the time of the Change of Control shall be assumed by, or replaced with grants that have comparable terms by, the surviving corporation (or a parent or subsidiary of the surviving corporation). After a Change of Control, references to the “Company” as they relate to employment matters shall include the successor employer in the transaction, subject to applicable law.

(b) Vesting Upon Certain Terminations of Employment. Unless the Grant Instrument provides otherwise, if a Participant’s employment is terminated by the Employer without Cause upon or within 12 months following a Change of Control, the Participant’s outstanding Grants shall become fully vested as of the date of such termination; provided that if the vesting of any such Grants is based, in whole or in part, on performance, the applicable Grant Instrument shall specify how the portion of the Grant that becomes vested pursuant to this Section 13(b) shall be calculated.

14

(c) Other Alternatives. In the event of a Change of Control, if any outstanding Grants are not assumed by, or replaced with grants that have comparable terms by, the surviving corporation (or a parent or subsidiary of the surviving corporation), the Committee may take any of the following actions with respect to any or all outstanding Grants, without the consent of any Participant: (i) the Committee may determine that outstanding Stock Options and SARs shall automatically accelerate and become fully exercisable and the restrictions and conditions on outstanding Stock Awards, Stock Units, Cash Awards and Dividend Equivalents shall immediately lapse; (ii) the Committee may determine that Participants shall receive a payment in settlement of outstanding Stock Units, Cash Awards or Dividend Equivalents, in such amount and form as may be determined by the Committee; (ii) the Committee may require that Participants surrender their outstanding Stock Options and SARs in exchange for a payment by the Company, in cash or Company Stock as determined by the Committee, in an amount equal to the amount, if any, by which the then Fair Market Value of the shares of Company Stock subject to the Participant’s unexercised Stock Options and SARs exceeds the Stock Option Exercise Price or SAR base amount, and (iv) after giving Participants an opportunity to exercise all of their outstanding Stock Options and SARs, the Committee may terminate any or all unexercised Stock Options and SARs at such time as the Committee deems appropriate. Such surrender, termination or payment shall take place as of the date of the Change of Control or such other date as the Committee may specify. Without limiting the foregoing, if the per share Fair Market Value of the Company Stock does not exceed the per share Stock Option Exercise Price or SAR base amount, as applicable, the Company shall not be required to make any payment to the Participant upon surrender of the Stock Option or SAR.

Section 14. Deferrals

The Committee may permit or require a Participant to defer receipt of the payment of cash or the delivery of shares that would otherwise be due to such Participant in connection with any Grant. If any such deferral election is permitted or required, the Committee shall establish rules and procedures for such deferrals and may provide for interest or other earnings to be paid on such deferrals. The rules and procedures for any such deferrals shall be consistent with applicable requirements of section 409A of the Code.

Section 15. Withholding of Taxes

(a) Required Withholding. All Grants under the Plan shall be subject to applicable United States federal (including FICA), state and local, foreign country or other tax withholding requirements. The Employer may require that the Participant or other person receiving Grants or exercising Grants pay to the Employer an amount sufficient to satisfy such tax withholding requirements with respect to such Grants, or the Employer may deduct from other wages and compensation paid by the Employer the amount of any withholding taxes due with respect to such Grants.

(b) Share Withholding. The Committee may permit or require the Employer’s tax withholding obligation with respect to Grants paid in Company Stock to be satisfied by having shares withheld up to an amount that does not exceed the Participant’s applicable

15

withholding tax rate for United States federal (including FICA), state and local tax liabilities. The Committee may, in its discretion, and subject to such rules as the Committee may adopt, allow Participants to elect to have such share withholding applied to all or a portion of the tax withholding obligation arising in connection with any particular Grant. Unless the Committee determines otherwise, share withholding for taxes shall not exceed the participant’s minimum applicable tax withholding amount.

Section 16. Transferability of Grants

(a) Nontransferability of Grants. Except as described in subsection (b) below, only the Participant may exercise rights under a Grant during the Participant’s lifetime. A Participant may not transfer those rights except (i) by will or by the laws of descent and distribution or (ii) with respect to Grants other than Incentive Stock Options, pursuant to a domestic relations order. When a Participant dies, the personal representative or other person entitled to succeed to the rights of the Participant may exercise such rights. Any such successor must furnish proof satisfactory to the Company of his or her right to receive the Grant under the Participant’s will or under the applicable laws of descent and distribution.

(b) Transfer of Nonqualified Stock Options. Notwithstanding the foregoing, the Committee may provide, in a Grant Instrument, that a Participant may transfer Nonqualified Stock Options to family members, or one or more trusts or other entities for the benefit of or owned by family members, consistent with the applicable securities laws, according to such terms as the Committee may determine; provided that the Participant receives no consideration for the transfer of an Option and the transferred Option shall continue to be subject to the same terms and conditions as were applicable to the Option immediately before the transfer.

Section 17. Requirements for Issuance or Transfer of Shares

No Company Stock shall be issued or transferred in connection with any Grant hereunder unless and until all legal requirements applicable to the issuance or transfer of such Company Stock have been complied with to the satisfaction of the Committee. The Committee shall have the right to condition any Grant on the Participant’s undertaking in writing to comply with such restrictions on his or her subsequent disposition of the shares of Company Stock as the Committee shall deem necessary or advisable, and certificates representing such shares may be legended to reflect any such restrictions. Certificates representing shares of Company Stock issued or transferred under the Plan may be subject to such stop-transfer orders and other restrictions as the Committee deems appropriate to comply with applicable laws, regulations and interpretations, including any requirement that a legend be placed thereon.

Section 18. Amendment and Termination of the Plan

(a) Amendment. The Board may amend or terminate the Plan at any time; provided, however, that the Board shall not amend the Plan without stockholder approval if such approval is required in order to comply with the Code or other applicable law, or to comply with applicable stock exchange requirements.

16

(b) Stockholder Approval Requirements.

(i) The Plan is intended to comply with the transition relief set forth at Treas. Reg. §1.162-27(f)(1) for companies that become publicly held in connection with an initial public offering, which applies until the first to occur of (A) the expiration of the Plan, (B) a material modification of the Plan within the meaning of section 162(m) of the Code and the regulations thereunder, (C) the issuance of all Company Stock authorized under the Plan, or (D) the first meeting of stockholders at which directors are to be elected that occurs after the close of the third calendar year following the calendar year in which the initial public offering occurs (the period commencing on the initial public offering and ending on the first to occur of the foregoing events shall be hereinafter referred to as the “Reliance Period”).

(ii) Following the Reliance Period, if Grants are to be made as “qualified performance-based compensation” under section 162(m) of the Code, the Plan must be approved by the stockholders in accordance with section 162(m) of the Code, and the Plan must be reapproved by the stockholders no later than the first stockholders meeting that occurs in the fifth year following the year in which the stockholders previously approved the Plan, if required by section 162(m) of the Code or the regulations thereunder.

(c) Termination of Plan. The Plan shall terminate on the day immediately preceding the tenth anniversary of its Effective Date, unless the Plan is terminated earlier by the Board or is extended by the Board with the approval of the stockholders.

(d) Termination and Amendment of Outstanding Grants. A termination or amendment of the Plan that occurs after a Grant is made shall not materially impair the rights of a Participant unless the Participant consents or unless the Committee acts under Section 19(f) below. The termination of the Plan shall not impair the power and authority of the Committee with respect to an outstanding Grant. Whether or not the Plan has terminated, an outstanding Grant may be terminated or amended under Section 19(f) below or may be amended by agreement of the Company and the Participant consistent with the Plan.

Section 19. Miscellaneous

(a) Grants in Connection with Corporate Transactions and Otherwise. Nothing contained in the Plan shall be construed to (i) limit the right of the Committee to make Grants under the Plan in connection with the acquisition, by purchase, lease, merger, consolidation or otherwise, of the business or assets of any corporation, firm or association, including Grants to employees thereof who become Employees, or (ii) limit the right of the Company to grant stock options or make other awards outside of the Plan. The Committee may make a Grant to an employee of another corporation who becomes an Employee by reason of a corporate merger, consolidation, acquisition of stock or property, reorganization or liquidation involving the Company, in substitution for a stock option or stock awards grant made by such corporation. Notwithstanding anything in the Plan to the contrary, the Committee may establish such terms and conditions of the new Grants as it deems appropriate, including setting the

17

Exercise Price of Options or the base price of SARs at a price necessary to retain for the Participant the same economic value as the prior options or rights.

(b) Governing Document. The Plan shall be the controlling document. No other statements, representations, explanatory materials or examples, oral or written, may amend the Plan in any manner. The Plan shall be binding upon and enforceable against the Company and its successors and assigns.

(c) Funding of the Plan. The Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the payment of any Grants under the Plan.

(d) Rights of Participants. Nothing in the Plan shall entitle any Employee, Non-Employee Director, Key Advisor or other person to any claim or right to receive a Grant under the Plan. Neither the Plan nor any action taken hereunder shall be construed as giving any individual any rights to be retained by or in the employ of the Employer or any other employment rights.

(e) No Fractional Shares. No fractional shares of Company Stock shall be issued or delivered pursuant to the Plan or any Grant. Except as otherwise provided under the Plan, the Committee shall determine whether cash, other awards or other property shall be issued or paid in lieu of such fractional shares or whether such fractional shares or any rights thereto shall be forfeited or otherwise eliminated.

(f) Compliance with Law.

(i) The Plan, the exercise of Options and SARs and the obligations of the Company to issue or transfer shares of Company Stock under Grants shall be subject to all applicable laws and regulations, and to approvals by any governmental or regulatory agency as may be required. With respect to persons subject to section 16 of the Exchange Act, it is the intent of the Company that the Plan and all transactions under the Plan comply with all applicable provisions of Rule 16b-3 or its successors under the Exchange Act. In addition, it is the intent of the Company that Incentive Stock Options comply with the applicable provisions of section 422 of the Code, and that, to the extent applicable, Grants comply with the requirements of section 409A of the Code. To the extent that any legal requirement of section 16 of the Exchange Act or section 422 or 409A of the Code as set forth in the Plan ceases to be required under section 16 of the Exchange Act or section 422 or 409A of the Code, that Plan provision shall cease to apply. The Committee may revoke any Grant if it is contrary to law or modify a Grant to bring it into compliance with any valid and mandatory government regulation. The Committee may also adopt rules regarding the withholding of taxes on payments to Participants. The Committee may, in its sole discretion, agree to limit its authority under this Section.

(ii) The Plan is intended to comply with the requirements of section 409A of the Code, to the extent applicable. Each Grant shall be construed and administered such that the Grant either (A) qualifies for an exemption from the requirements of section 409A of the

18

Code or (B) satisfies the requirements of section 409A of the Code. If a Grant is subject to section 409A of the Code, (I) distributions shall only be made in a manner and upon an event permitted under section 409A of the Code, (II) payments to be made upon a termination of employment or service shall only be made upon a “separation from service” under section 409A of the Code, (III) unless the Grant specifies otherwise, each installment payment shall be treated as a separate payment for purposes of section 409A of the Code, and (IV) in no event shall a Participant, directly or indirectly, designate the calendar year in which a distribution is made except in accordance with section 409A of the Code.

(iii) Any Grant that is subject to section 409A of the Code and that is to be distributed to a Key Employee (as defined below) upon separation from service shall be administered so that any distribution with respect to such Grant shall be postponed for six months following the date of the Participant’s separation from service, if required by section 409A of the Code. If a distribution is delayed pursuant to section 409A of the Code, the distribution shall be paid within 15 days after the end of the six-month period. If the Participant dies during such six-month period, any postponed amounts shall be paid within 90 days of the Participant’s death. The determination of Key Employees, including the number and identity of persons considered Key Employees and the identification date, shall be made by the Committee or its delegate each year in accordance with section 416(i) of the Code and the “specified employee” requirements of section 409A of the Code.

(iv) Notwithstanding anything in the Plan or any Grant agreement to the contrary, each Participant shall be solely responsible for the tax consequences of Grants under the Plan, and in no event shall the Company or any subsidiary or affiliate of the Company have any responsibility or liability if a Grant does not meet any applicable requirements of section 409A of the Code. Although the Company intends to administer the Plan to prevent taxation under section 409A of the Code, the Company does not represent or warrant that the Plan or any Grant complies with any provision of federal, state, local or other tax law.

(g) Establishment of Subplans. The Board may from time to time establish one or more sub-plans under the Plan for purposes of satisfying applicable blue sky, securities or tax laws of various jurisdictions. The Board shall establish such sub-plans by adopting supplements to the Plan setting forth (i) such limitations on the Committee’s discretion under the Plan as the Board deems necessary or desirable and (ii) such additional terms and conditions not otherwise inconsistent with the Plan as the Board shall deem necessary or desirable. All supplements adopted by the Board shall be deemed to be part of the Plan, but each supplement shall apply only to Participants within the affected jurisdiction and the Employer shall not be required to provide copies of any supplement to Participants in any jurisdiction that is not affected.

(h) Clawback Rights. Subject to the requirements of applicable law, the Committee may provide in any Grant Instrument that, if a Participant breaches any restrictive covenant agreement between the Participant and the Employer (which may be set forth in any Grant Instrument) or otherwise engages in activities that constitute Cause either while employed by, or providing service to, the Employer or within a specified period of time thereafter, all

19

Grants held by the Participant shall terminate, and the Company may rescind any exercise of an Option or SAR and the vesting of any other Grant and delivery of shares upon such exercise or vesting (including pursuant to dividends and Dividend Equivalents), as applicable on such terms as the Committee shall determine, including the right to require that in the event of any such rescission, (i) the Participant shall return to the Company the shares received upon the exercise of any Option or SAR and/or the vesting and payment of any other Grant (including pursuant to dividends and Dividend Equivalents) or, (ii) if the Participant no longer owns the shares, the Participant shall pay to the Company the amount of any gain realized or payment received as a result of any sale or other disposition of the shares (or, in the event the Participant transfers the shares by gift or otherwise without consideration, the Fair Market Value of the shares on the date of the breach of the restrictive covenant agreement (including a Participant’s Grant Instrument containing restrictive covenants) or activity constituting Cause), net of the price originally paid by the Participant for the shares. Payment by the Participant shall be made in such manner and on such terms and conditions as may be required by the Committee. The Employer shall be entitled to set off against the amount of any such payment any amounts otherwise owed to the Participant by the Employer. In addition, all Grants under the Plan shall be subject to any applicable clawback or recoupment policies, share trading policies and other policies that may be implemented by the Board from time to time.

(i) Governing Law; Jurisdiction. The validity, construction, interpretation and effect of the Plan and Grant Instruments issued under the Plan shall be governed and construed by and determined in accordance with the laws of the State of Delaware, without giving effect to the conflict of laws provisions thereof. Any action arising out of, or relating to, any of the provisions of the Plan and Grants made hereunder shall be brought only in the United States District Court for the District of Massachusetts, or if such court does not have jurisdiction or will not accept jurisdiction, in any court of general jurisdiction in Boston Massachusetts, and the jurisdiction of such court in any such proceeding shall be exclusive. Notwithstanding the foregoing sentence, on and after the date a Participant receives shares of Company Stock hereunder, the Participant will be subject to the jurisdiction provision set forth in the Corporation’s bylaws.

OMNIBUS INCENTIVE COMPENSATION PLAN

NONQUALIFIED STOCK OPTION GRANT AGREEMENT

This NONQUALIFIED STOCK OPTION GRANT AGREEMENT (the “Agreement”), dated as of (the “Date of Grant”), is delivered by CarGurus, Inc. (the “Company”) to (the “Participant”).

RECITALS

The CarGurus, Inc. Omnibus Incentive Compensation Plan (the “Plan”) provides for the grant of stock options to purchase shares of Class A common stock of the Company (“Company Stock”). The Committee has decided to make this nonqualified stock option grant as an inducement for the Participant to promote the best interests of the Company and its stockholders. The Participant hereby acknowledges the receipt of a copy of the official prospectus for the Plan, which is available by accessing the Company’s intranet at [Insert link]. Paper copies of the Plan and the official Plan prospectus are available by contacting the Senior Vice President, General Counsel of the Company at 617.315.4900 or legal@cargurus.com. This Agreement is made pursuant to the Plan and is subject in its entirety to all applicable provisions of the Plan. Capitalized terms used herein and not otherwise defined will have the meanings set forth in the Plan.

1. Grant of Option. Subject to the terms and conditions set forth in this Agreement and in the Plan, the Company hereby grants to the Participant a nonqualified stock option (the “Option”) to purchase shares of Company Stock (“Shares”) at an Exercise Price of $ per Share. The Option shall become exercisable according to Section 2 below.

2. Exercisability of Option.

(a) The Option shall become vested and exercisable on the following dates (each, a “Vesting Date”), provided that the Participant continues to be employed by, or provide service to, the Employer from the Date of Grant until the applicable Vesting Date:

Vesting Date |  | Percentage of Shares for Which the Option is Exercisable as of the Vesting Date

(b) The vesting and exercisability of the Option is cumulative, but shall not exceed 100% of the Shares subject to the Option. If the foregoing schedule would produce fractional Shares, the number of Shares for which the Option becomes vested and exercisable shall be rounded down to the nearest whole Share and the fractional Shares will be accumulated so that the resulting whole Shares will be included in the number of Shares for which the Option becomes vested and exercisable on the last Vesting Date.

(c) Except as otherwise provided in a written employment agreement or severance agreement entered into by and between the Participant and the Employer, in the event of a Change of Control before the Option is fully vested and exercisable, the provisions of the Plan applicable to a Change of Control shall apply to the Option, and, in the event of a Change of Control, the Committee may take such actions with respect to the vesting and exercisability of the Option as it deems appropriate pursuant to the Plan.

Notwithstanding the foregoing, if the Company is not the surviving corporation (or survives only as a subsidiary of another corporation) as a result of the Change of Control and the Option is assumed by, or replaced with an award with comparable terms by, the surviving corporation (or parent or subsidiary of the surviving corporation) and the Participant’s employment is terminated by the Employer without Cause upon or within 12 months following a Change of Control and before the Option is fully vested and exercisable in accordance with the vesting schedule set forth in Section 2(a) above, any unvested and unexercisable portion of the Option shall become fully vested and exercisable upon such termination of employment.

3. Term of Option.

(a) The Option shall have a term of ten years from the Date of Grant and shall terminate at the expiration of that period, unless it is terminated at an earlier date pursuant to the provisions of this Agreement or the Plan. Notwithstanding the foregoing, in the event that on the last business day of the term of the Option, the exercise of the Option is prohibited by applicable law, including a prohibition on purchases or sales of Company Stock under the Company’s insider trading policy, the term of the Option shall be extended for a period of 30 days following the end of the legal prohibition, unless the Committee determines otherwise.

(b) The Option shall automatically terminate upon the happening of the first of the following events:

(i) The expiration of the 90-day period after the Participant ceases to be employed by, or provide service to, the Employer, if the termination is for any reason other than Disability, death or Cause.

(ii) The expiration of the one-year period after the Participant ceases to be employed by, or provide service to, the Employer on account of the Participant’s Disability.

(iii) The expiration of the one-year period after the Participant ceases to be employed by, or provide service to, the Employer, if the Participant dies while employed by, or providing service to, the Employer or the Participant dies within 90 days after the Participant ceases to be so employed or to provide services to the Employer for any reason other than Disability, death or Cause.

(iv) The date on which the Participant ceases to be employed by, or provide service to, the Employer for Cause. In addition, notwithstanding the prior provisions of this Section 3, if the Participant engages in conduct that constitutes Cause after the Participant’s employment or service terminates, the Option shall immediately terminate.

2

Notwithstanding the foregoing, in no event may the Option be exercised after the date that is immediately before the tenth anniversary of the Date of Grant, except as provided under Section 3(a) above. Any portion of the Option that is not exercisable at the time the Participant ceases to be employed by, or provide service to, the Employer shall immediately terminate.

4. Exercise Procedures.

(a) Subject to the provisions of Sections 2 and 3 above, the Participant may exercise part or all of the exercisable Option by giving the Company or its delegate written notice of intent to exercise, specifying the number of shares of Company Stock as to which the Option is to be exercised and such other information as the Company or its delegate may require.

At such time as the Committee shall determine, the Participant shall pay the Exercise Price (i) in cash, (ii) unless the Committee determines otherwise, by delivering shares of Company Stock owned by the Participant, which shall be valued at their Fair Market Value on the date of exercise, or by attestation (in accordance with procedures prescribed by the Company) to ownership of shares of Company Stock having a Fair Market Value on the date of exercise at least equal to the Exercise Price, (iii) by payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board, (iv) by surrendering shares of Company Stock subject to the exercisable Option for an appreciation distribution payable in Shares with a Fair Market Value on the date of exercise equal to the dollar amount by which the then Fair Market Value of the Shares subject to the surrendered portion exceeds the aggregate Exercise Price payable for the Shares (“net exercise”), or (v) by such other method as the Committee may approve, to the extent permitted by applicable law. The Committee may impose from time to time such limitations as it deems appropriate on the use of shares of Company Stock to exercise the Option.

(b) The obligation of the Company to deliver Shares upon exercise of the Option shall be subject to all applicable laws, rules, and regulations and such approvals by governmental agencies as may be deemed appropriate by the Committee, including such actions as Company counsel shall deem necessary or appropriate to comply with relevant securities laws and regulations.

(c) All obligations of the Company under this Agreement shall be subject to the rights of the Employer as set forth in the Plan to withhold amounts required to be withheld for any taxes, if applicable. The Participant shall be required to pay to the Employer, or make other arrangements satisfactory to the Employer to provide for the payment of, any federal, state, local or other taxes that the Employer is required to withhold with respect to the Option. The Participant may elect to satisfy any tax withholding obligation of the Employer with respect to the Option by having Shares withheld to satisfy the applicable withholding tax rate for federal (including FICA), state, local and other tax liabilities. Unless the Committee determines otherwise, share withholding for taxes shall not exceed the Participant’s minimum applicable tax withholding amount.

(d) Upon exercise of the Option (or portion thereof), the Option (or portion thereof) will terminate and cease to be outstanding.

3

5. Restrictions on Exercise. Except as the Committee may otherwise permit pursuant to the Plan, only the Participant may exercise the Option during the Participant’s lifetime and, after the Participant’s death, the Option shall be exercisable (subject to the limitations specified in the Plan) solely by the legal representatives of the Participant, or by the person who acquires the right to exercise the Option by will or by the laws of descent and distribution, to the extent that the Option is exercisable pursuant to this Agreement.

6. Grant Subject to Plan Provisions. This grant is made pursuant to the Plan, the terms of which are incorporated herein by reference, and in all respects shall be interpreted in accordance with the Plan. The grant and exercise of the Option are subject to the provisions of the Plan and to interpretations, regulations and determinations concerning the Plan established from time to time by the Committee in accordance with the provisions of the Plan, including, but not limited to, provisions pertaining to (a) rights and obligations with respect to withholding taxes, (b) the registration, qualification or listing of the Shares, (c) changes in capitalization of the Company and (d) other requirements of applicable law. The Committee shall have the authority to interpret and construe the Option pursuant to the terms of the Plan, and its decisions shall be conclusive as to any questions arising hereunder.

7. No Employment or Other Rights. The grant of the Option shall not confer upon the Participant any right to be retained by or in the employ or service of any Employer and shall not interfere in any way with the right of any Employer to terminate the Participant’s employment or service at any time. The right of any Employer to terminate at will the Participant’s employment or service at any time for any reason is specifically reserved.

8. No Stockholder Rights. Neither the Participant, nor any person entitled to exercise the Participant’s rights in the event of the Participant’s death, shall have any of the rights and privileges of a stockholder with respect to the Shares subject to the Option, until certificates for Shares have been issued upon the exercise of the Option.

9. Assignment and Transfers. Except as the Committee may otherwise permit pursuant to the Plan, the rights and interests of the Participant under this Agreement may not be sold, assigned, encumbered or otherwise transferred except, in the event of the death of the Participant, by will or by the laws of descent and distribution. In the event of any attempt by the Participant to alienate, assign, pledge, hypothecate, or otherwise dispose of the Option or any right hereunder, except as provided for in this Agreement, or in the event of the levy or any attachment, execution or similar process upon the rights or interests hereby conferred, the Company may terminate the Option by notice to the Participant, and the Option and all rights hereunder shall thereupon become null and void. The rights and protections of the Company hereunder shall extend to any successors or assigns of the Company and to the Company’s parents, subsidiaries, and affiliates. This Agreement may be assigned by the Company without the Participant’s consent.

10. Applicable Law; Jurisdiction. The validity, construction, interpretation and effect of this Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the conflicts of laws provisions thereof. Any action arising out of, or relating to, any of the provisions of this Agreement shall be brought only in the United States District Court for the District of Massachusetts, or if such court does not have jurisdiction

4

or will not accept jurisdiction, in any court of general jurisdiction in Boston, Massachusetts, and the jurisdiction of such court in any such proceeding shall be exclusive. Notwithstanding the foregoing sentence, on and after the date a Participant receives shares of Company Stock hereunder, the Participant will be subject to the jurisdiction provision set forth in the Corporation’s bylaws.

11. Notice. Any notice to the Company provided for in this instrument shall be addressed to the Company in care of the Senior Vice President, General Counsel, with copy to the Chief Financial Officer at the corporate headquarters of the Company, and any notice to the Participant shall be addressed to such Participant at the current address shown on the payroll of the Employer, or to such other address as the Participant may designate to the Employer in writing. Any notice shall be delivered by hand or enclosed in a properly sealed envelope addressed as stated above, registered and deposited, postage prepaid, in a post office regularly maintained by the United States Postal Service or by the postal authority of the country in which the Participant resides or to an internationally recognized expedited mail courier.

12. Recoupment Policy. The Participant agrees that, subject to the requirements of applicable law, if the Participant breaches any restrictive covenant agreement between the Participant and the Employer or otherwise engages in activities that constitute Cause either while employed by, or providing service to, the Employer or within 12 months thereafter, the Option shall terminate, and the Company may rescind any exercise of the Option and delivery of Shares upon such exercise, as applicable on such terms as the Committee shall determine, including the right to require that in the event of any such rescission (a) the Participant shall return to the Company the Shares received upon the exercise of the Option or, (b) if the Participant no longer owns the Shares, the Participant shall pay to the Company the amount of any gain realized or payment received as a result of any sale or other disposition of the Shares (or, in the event the Participant transfers the Shares by gift or otherwise without consideration, the Fair Market Value of the Shares on the date of the breach of any restrictive covenant agreement or activity constituting Cause), net of the price originally paid by the Participant for the Shares. The Participant agrees that payment by the Participant shall be made in such manner and on such terms and conditions as may be required by the Committee and the Employer shall be entitled to set off against the amount of any such payment any amounts otherwise owed to the Participant by the Employer. In addition, the Participant agrees that the Option shall be subject to any applicable clawback or recoupment policies, share trading policies and other policies that may be implemented by the Board or imposed under applicable rule or regulation from time to time.

13. Application of Section 409A of the Code. This Agreement is intended to be exempt from section 409A of the Code and to the extent this Agreement is subject to section 409A of the Code, it will in all respects be administered in accordance with section 409A of the Code.

INCENTIVE STOCK OPTION GRANT AGREEMENT

This INCENTIVE STOCK OPTION GRANT AGREEMENT (the “Agreement”), dated as of (the “Date of Grant”), is delivered by CarGurus, Inc. (the “Company”) to (the “Participant”).

RECITALS

The CarGurus, Inc. Omnibus Incentive Compensation Plan (the “Plan”) provides for the grant of stock options to purchase shares of Class A common stock of the Company (“Company Stock”). The Committee has decided to make this incentive stock option grant as an inducement for the Participant to promote the best interests of the Company and its stockholders. The Participant hereby acknowledges the receipt of a copy of the official prospectus for the Plan, which is available by accessing the Company’s intranet at [Insert link]. Paper copies of the Plan and the official Plan prospectus are available by contacting the Senior Vice President, General Counsel of the Company at 617.315.4900 or legal@cargurus.com. This Agreement is made pursuant to the Plan and is subject in its entirety to all applicable provisions of the Plan. Capitalized terms used herein and not otherwise defined will have the meanings set forth in the Plan.

1. Grant of Option.

(a) Subject to the terms and conditions set forth in this Agreement and in the Plan, the Company hereby grants to the Participant an incentive stock option (the “Option”) to purchase shares of Company Stock (“Shares”) at an Exercise Price of $ per Share. The Option shall become exercisable according to Section 2 below.

(b) The Option is designated as an incentive stock option, as described in Section 5 below. However, if and to the extent the Option exceeds the limits for an incentive stock option, as described in Section 5, the Option shall be a nonqualified stock option.

2. Exercisability of Option.

(a) The Option shall become vested and exercisable on the following dates (each, a “Vesting Date”), provided that the Participant continues to be employed by, or provide service to, the Employer from the Date of Grant until the applicable Vesting Date:

Vesting Date |  | Percentage of Shares for Which the Option is Exercisable as of the Vesting Date

(b) The vesting and exercisability of the Option is cumulative, but shall not exceed 100% of the Shares subject to the Option. If the foregoing schedule would produce fractional Shares, the number of Shares for which the Option becomes vested and exercisable shall be rounded down to the nearest whole Share and the fractional Shares will be accumulated so that the resulting whole Shares will be included in the number of Shares for which the Option becomes vested and exercisable on the last Vesting Date.

(c) Except as otherwise provided in a written employment agreement or severance agreement entered into by and between the Participant and the Employer, in the event of a Change of Control before the Option is fully vested and exercisable, the provisions of the Plan applicable to a Change of Control shall apply to the Option, and, in the event of a Change of Control, the Committee may take such actions with respect to the vesting and exercisability of the Option as it deems appropriate pursuant to the Plan.

Notwithstanding the foregoing, if the Company is not the surviving corporation (or survives only as a subsidiary of another corporation) as a result of the Change of Control and the Option is assumed by, or replaced with an award with comparable terms by, the surviving corporation (or parent or subsidiary of the surviving corporation) and the Participant’s employment is terminated by the Employer without Cause upon or within 12 months following a Change of Control and before the Option is fully vested and exercisable in accordance with the vesting schedule set forth in Section 2(a) above, any unvested and unexercisable portion of the Option shall become fully vested and exercisable upon such termination of employment.

3. Term of Option.

(a) The Option shall have a term of ten years from the Date of Grant and shall terminate at the expiration of that period, unless it is terminated at an earlier date pursuant to the provisions of this Agreement or the Plan. Notwithstanding the foregoing, in the event that on the last business day of the term of the Option, the exercise of the Option is prohibited by applicable law, including a prohibition on purchases or sales of Company Stock under the Company’s insider trading policy, the term of the Option shall be extended for a period of 30 days following the end of the legal prohibition, unless the Committee determines otherwise.

(b) The Option shall automatically terminate upon the happening of the first of the following events:

(i) The expiration of the 90-day period after the Participant ceases to be employed by, or provide service to, the Employer, if the termination is for any reason other than Disability, death or Cause.

(ii) The expiration of the one-year period after the Participant ceases to be employed by, or provide service to, the Employer on account of the Participant’s Disability.

(iii) The expiration of the one-year period after the Participant ceases to be employed by, or provide service to, the Employer, if the Participant dies while employed by, or providing service to, the Employer or the Participant dies within 90 days after the

2

Participant ceases to be so employed or to provide services to the Employer for any reason other than Disability, death or Cause.

(iv) The date on which the Participant ceases to be employed by, or provide service to, the Employer for Cause. In addition, notwithstanding the prior provisions of this Section 3, if the Participant engages in conduct that constitutes Cause after the Participant’s employment or service terminates, the Option shall immediately terminate.

Notwithstanding the foregoing, in no event may the Option be exercised after the date that is immediately before the tenth anniversary of the Date of Grant, except as provided under Section 3(a) above. Any portion of the Option that is not exercisable at the time the Participant ceases to be employed by, or provide service to, the Employer shall immediately terminate.

4. Exercise Procedures.

(a) Subject to the provisions of Sections 2 and 3 above, the Participant may exercise part or all of the exercisable Option by giving the Company or its delegate written notice of intent to exercise, specifying the number of shares of Company Stock as to which the Option is to be exercised and such other information as the Company or its delegate may require.

At such time as the Committee shall determine, the Participant shall pay the Exercise Price (i) in cash, (ii) unless the Committee determines otherwise, by delivering shares of Company Stock owned by the Participant, which shall be valued at their Fair Market Value on the date of exercise, or by attestation (in accordance with procedures prescribed by the Company) to ownership of shares of Company Stock having a Fair Market Value on the date of exercise at least equal to the Exercise Price, (iii) by payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board, (iv) by surrendering shares of Company Stock subject to the exercisable Option for an appreciation distribution payable in Shares with a Fair Market Value on the date of exercise equal to the dollar amount by which the then Fair Market Value of the Shares subject to the surrendered portion exceeds the aggregate Exercise Price payable for the Shares (“net exercise”), or (v) by such other method as the Committee may approve, to the extent permitted by applicable law. The Committee may impose from time to time such limitations as it deems appropriate on the use of shares of Company Stock to exercise the Option.

(b) The obligation of the Company to deliver Shares upon exercise of the Option shall be subject to all applicable laws, rules, and regulations and such approvals by governmental agencies as may be deemed appropriate by the Committee, including such actions as Company counsel shall deem necessary or appropriate to comply with relevant securities laws and regulations.

(c) All obligations of the Company under this Agreement shall be subject to the rights of the Employer as set forth in the Plan to withhold amounts required to be withheld for any taxes, if applicable. The Participant shall be required to pay to the Employer, or make other arrangements satisfactory to the Employer to provide for the payment of, any federal, state, local or other taxes that the Employer is required to withhold with respect to the Option. The Participant may elect to satisfy any tax withholding obligation of the Employer with respect to

3

the Option by having Shares withheld to satisfy the applicable withholding tax rate for federal (including FICA), state, local and other tax liabilities. Unless the Committee determines otherwise, share withholding for taxes shall not exceed the Participant’s minimum applicable tax withholding amount.

(d) Upon exercise of the Option (or portion thereof), the Option (or portion thereof) will terminate and cease to be outstanding.

5. Designation as Incentive Stock Option.

(a) This Option is designated an incentive stock option under Section 422 of the Code. If the aggregate fair market value of the stock on the date of the grant with respect to which incentive stock options are exercisable for the first time by the Participant during any calendar year, under the Plan or any other stock option plan of the Company or a parent or subsidiary, exceeds $100,000, then the Option, as to the excess, shall be treated as a nonqualified stock option that does not meet the requirements of Section 422. If and to the extent that the Option fails to qualify as an incentive stock option under the Code, the Option shall remain outstanding according to its terms as a nonqualified stock option.

(b) The Participant understands that favorable incentive stock option tax treatment is available only if the Option is exercised while the Participant is an employee of the Company or a parent or subsidiary of the Company or within a period of time specified in the Code after the Participant ceases to be an employee. The Participant understands that the Participant is responsible for the income tax consequences of the Option, and, among other tax consequences, the Participant understands that he or she may be subject to the alternative minimum tax under the Code in the year in which the Option is exercised. The Participant will consult with his or her tax adviser regarding the tax consequences of the Option.

6. Restrictions on Exercise. Only the Participant may exercise the Option during the Participant’s lifetime. After the Participant’s death, the Option shall be exercisable (subject to the limitations specified in the Plan) solely by the legal representatives of the Participant, or by the person who acquires the right to exercise the Option by will or by the laws of descent and distribution, to the extent that the Option is exercisable pursuant to this Agreement.

7. Grant Subject to Plan Provisions. This grant is made pursuant to the Plan, the terms of which are incorporated herein by reference, and in all respects shall be interpreted in accordance with the Plan. The grant and exercise of the Option are subject to the provisions of the Plan and to interpretations, regulations and determinations concerning the Plan established from time to time by the Committee in accordance with the provisions of the Plan, including, but not limited to, provisions pertaining to (a) rights and obligations with respect to withholding taxes, (b) the registration, qualification or listing of the Shares, (c) changes in capitalization of the Company and (d) other requirements of applicable law. The Committee shall have the authority to interpret and construe the Option pursuant to the terms of the Plan, and its decisions shall be conclusive as to any questions arising hereunder.

8. No Employment or Other Rights. The grant of the Option shall not confer upon the Participant any right to be retained by or in the employ or service of any Employer and shall not

4

interfere in any way with the right of any Employer to terminate the Participant’s employment or service at any time. The right of any Employer to terminate at will the Participant’s employment or service at any time for any reason is specifically reserved.

9. No Stockholder Rights. Neither the Participant, nor any person entitled to exercise the Participant’s rights in the event of the Participant’s death, shall have any of the rights and privileges of a stockholder with respect to the Shares subject to the Option, until certificates for Shares have been issued upon the exercise of the Option.

10. Assignment and Transfers. The rights and interests of the Participant under this Agreement may not be sold, assigned, encumbered or otherwise transferred except, in the event of the death of the Participant, by will or by the laws of descent and distribution. In the event of any attempt by the Participant to alienate, assign, pledge, hypothecate, or otherwise dispose of the Option or any right hereunder, except as provided for in this Agreement, or in the event of the levy or any attachment, execution or similar process upon the rights or interests hereby conferred, the Company may terminate the Option by notice to the Participant, and the Option and all rights hereunder shall thereupon become null and void. The rights and protections of the Company hereunder shall extend to any successors or assigns of the Company and to the Company’s parents, subsidiaries, and affiliates. This Agreement may be assigned by the Company without the Participant’s consent.

11. Applicable Law; Jurisdiction. The validity, construction, interpretation and effect of this Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the conflicts of laws provisions thereof. Any action arising out of, or relating to, any of the provisions of this Agreement shall be brought only in the United States District Court for the District of Massachusetts, or if such court does not have jurisdiction or will not accept jurisdiction, in any court of general jurisdiction in Boston, Massachusetts, and the jurisdiction of such court in any such proceeding shall be exclusive. Notwithstanding the foregoing sentence, on and after the date a Participant receives shares of Company Stock hereunder, the Participant will be subject to the jurisdiction provision set forth in the Corporation’s bylaws.

12. Notice. Any notice to the Company provided for in this instrument shall be addressed to the Company in care of the Senior Vice President, General Counsel, with copy to the Chief Financial Officer at the corporate headquarters of the Company, and any notice to the Participant shall be addressed to such Participant at the current address shown on the payroll of the Employer, or to such other address as the Participant may designate to the Employer in writing. Any notice shall be delivered by hand or enclosed in a properly sealed envelope addressed as stated above, registered and deposited, postage prepaid, in a post office regularly maintained by the United States Postal Service or by the postal authority of the country in which the Participant resides or to an internationally recognized expedited mail courier.

13. Recoupment Policy. The Participant agrees that, subject to the requirements of applicable law, if the Participant breaches any restrictive covenant agreement between the Participant and the Employer or otherwise engages in activities that constitute Cause either while employed by, or providing service to, the Employer or within 12 months thereafter, the Option shall terminate, and the Company may rescind any exercise of the Option and delivery of Shares

5

upon such exercise, as applicable on such terms as the Committee shall determine, including the right to require that in the event of any such rescission (a) the Participant shall return to the Company the Shares received upon the exercise of the Option or, (b) if the Participant no longer owns the Shares, the Participant shall pay to the Company the amount of any gain realized or payment received as a result of any sale or other disposition of the Shares (or, in the event the Participant transfers the Shares by gift or otherwise without consideration, the Fair Market Value of the Shares on the date of the breach of any restrictive covenant agreement or activity constituting Cause), net of the price originally paid by the Participant for the Shares. The Participant agrees that payment by the Participant shall be made in such manner and on such terms and conditions as may be required by the Committee and the Employer shall be entitled to set off against the amount of any such payment any amounts otherwise owed to the Participant by the Employer. In addition, the Participant agrees that the Option shall be subject to any applicable clawback or recoupment policies, share trading policies and other policies that may be implemented by the Board or imposed under applicable rule or regulation from time to time.

This RESTRICTED STOCK UNIT AGREEMENT (the “Agreement”), dated as of (the “Date of Grant”), is delivered by CarGurus, Inc. (the “Company”) to (the “Participant”).

RECITALS

The CarGurus, Inc. Omnibus Incentive Compensation Plan (the “Plan”) provides for the grant of restricted stock units. The Committee has decided to make this grant of restricted stock units as an inducement for the Participant to promote the best interests of the Company and its stockholders. The Participant hereby acknowledges the receipt of a copy of the official prospectus for the Plan, which is available by accessing the Company’s intranet at [Insert link]. Paper copies of the Plan and the official Plan prospectus are available by contacting the Senior Vice President, General Counsel of the Company at 617.315.4900 or legal@cargurus.com. This Agreement is made pursuant to the Plan and is subject in its entirety to all applicable provisions of the Plan. Capitalized terms used herein and not otherwise defined will have the meanings set forth in the Plan.

1. Grant of Stock Units. Subject to the terms and conditions set forth in this Agreement and in the Plan, the Company hereby grants the Participant restricted stock units, subject to the restrictions set forth below and in the Plan (the “Stock Units”). Each Stock Unit represents the right of the Participant to receive a share of Class A common stock of the Company (“Company Stock”) on the applicable payment date set forth in Section 5 below.

2. Stock Unit Account. Stock Units represent hypothetical shares of Company Stock, and not actual shares of stock. The Company shall establish and maintain a Stock Unit account, as a bookkeeping account on its records, for the Participant and shall record in such account the number of Stock Units granted to the Participant. No shares of Company Stock shall be issued to the Participant at the time the grant is made, and the Participant shall not be, and shall not have any of the rights or privileges of, a stockholder of the Company with respect to any Stock Units recorded in the Stock Unit account. The Participant shall not have any interest in any fund or specific assets of the Company by reason of this award or the Stock Unit account established for the Participant.

3. Vesting.

(a) The Stock Units shall become vested according to the following schedule (each, a “Vesting Date”), provided that the Participant continues to be employed by, or provide service to, the Employer from the Date of Grant until the applicable Vesting Date:

Vesting Date |  | Vested Stock Units

(b) The vesting of the Stock Units shall be cumulative, but shall not exceed 100% of the Stock Units. If the foregoing schedule would produce fractional Stock Units, the number of Stock Units that vest shall be rounded down to the nearest whole Stock Unit and the fractional Stock Units will be accumulated so that the resulting whole Stock Units will be included in the number of Stock Units that become vested on the last Vesting Date.

(c) Except as otherwise provided in a written employment agreement or severance agreement entered into by and between the Participant and the Employer, in the event of a Change of Control before all of the Stock Units vest in accordance with Section 3(a) above, the provisions of the Plan applicable to a Change of Control shall apply to the Stock Units, and, in the event of a Change of Control, the Committee may take such actions with respect to the vesting of the Stock Units as it deems appropriate pursuant to the Plan.

Notwithstanding the foregoing, if the Company is not the surviving corporation (or survives only as a subsidiary of another corporation) as a result of the Change of Control and the Stock Units are assumed by, or replaced with an award with comparable terms by, the surviving corporation (or parent or subsidiary of the surviving corporation) and the Participant’s employment is terminated by the Employer without Cause upon or within 12 months following a Change of Control and before the Stock Units are fully vested in accordance with the vesting schedule set forth in Section 3(a) above, any unvested Stock Units shall become fully vested upon such termination of employment.

4. Termination of Stock Units. If the Participant ceases to be employed by, or provide service to, the Employer for any reason before all of the Stock Units vest, any unvested Stock Units shall automatically terminate and shall be forfeited as of the date of the Participant’s termination of employment or service. No payment shall be made with respect to any unvested Stock Units that terminate as described in this Section 4.

5. Payment of Stock Units.

(a) If and when the Stock Units vest, the Company shall issue to the Participant one share of Company Stock for each vested Stock Unit, subject to applicable tax withholding obligations. Payment shall be made within 30 days after the applicable Vesting Date.

(b) All obligations of the Company under this Agreement shall be subject to the rights of the Employer as set forth in the Plan to withhold amounts required to be withheld for any taxes, if applicable. At the time of payment in accordance with Section 5(a) above, the number of shares issued to the Participant shall be reduced by a number of shares of Company Stock with a Fair Market Value (measured as of the Vesting Date) equal to an amount of the federal (including FICA), state, local and other tax liabilities required by law to be withheld with respect

2

to the payment of the Stock Units. To the extent not withheld in accordance with the immediately preceding sentence, the Participant shall be required to pay to the Employer, or make other arrangements satisfactory to the Employer to provide for the payment of, any federal, state, local or other taxes that the Employer is required to withhold with respect to the Stock Units. Unless the Committee determines otherwise, share withholding for taxes shall not exceed the Participant’s minimum applicable tax withholding amount.

(c) The obligation of the Company to deliver Company Stock shall also be subject to the condition that if at any time the Board shall determine in its discretion that the listing, registration or qualification of the shares upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance of shares, the shares may not be issued in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Board. The issuance of shares to Participant pursuant to this Agreement is subject to any applicable taxes and other laws or regulations of the United States or of any state having jurisdiction thereof.

6. No Stockholder Rights; Dividend Equivalents. Neither the Participant, nor any person entitled to receive payment in the event of the Participant’s death, shall have any of the rights and privileges of a stockholder with respect to shares of Company Stock, including voting or dividend rights, until certificates for shares have been issued upon payment of Stock Units. The Participant acknowledges that no election under Section 83(b) of the Code is available with respect to Stock Units. Notwithstanding the foregoing, the Participant shall be entitled to accrue Dividend Equivalents on the shares underlying the Stock Units prior to the Vesting Date, which shall be credited to the Stock Unit account for the Participant and will be paid or distributed in the form of shares Company Stock when the shares underlying the Stock Units vest and are issued in accordance with this Agreement.

7. Grant Subject to Plan Provisions. This grant is made pursuant to the Plan, the terms of which are incorporated herein by reference, and in all respects shall be interpreted in accordance with the Plan. The grant and payment of the Stock Units are subject to the provisions of the Plan and to interpretations, regulations and determinations concerning the Plan established from time to time by the Committee in accordance with the provisions of the Plan, including, but not limited to, provisions pertaining to (a) rights and obligations with respect to withholding taxes, (b) the registration, qualification or listing of the shares of Company Stock, (c) changes in capitalization of the Company and (d) other requirements of applicable law. The Committee shall have the authority to interpret and construe the Stock Units pursuant to the terms of the Plan, and its decisions shall be conclusive as to any questions arising hereunder.

8. No Employment or Other Rights. The grant of the Stock Units shall not confer upon the Participant any right to be retained by or in the employ or service of any Employer and shall not interfere in any way with the right of any Employer to terminate the Participant’s employment or service at any time. The right of any Employer to terminate at will the Participant’s employment or service at any time for any reason is specifically reserved.
