<p align="left" style="margin:0in 0in .0001pt;text-align:left;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On January&nbsp;3,
2005, Rush Enterprises, Inc., a Texas corporation (the &#147;Company&#148;), completed
the acquisition (the &#147;Acquisition&#148;) of Peterbilt dealerships in Dallas, Fort
Worth, Abilene and Tyler, Texas and Nashville, Tennessee from American Truck
Source, Inc. (&#147;ATS&#148;), pursuant to the Asset Purchase Agreement dated as of September&nbsp;15,
2004 to which the Company and ATS are parties (the &#147;Agreement&#148;).&nbsp; The Agreement
was filed as Exhibit 2.1 on the Company&#146;s current report on Form 8-K dated September&nbsp;16,
2004 and incorporated herein by reference.&nbsp; The Company and ATS amended
the Agreement on November&nbsp;8, 2004 and the amendment was filed as Exhibit
2.1 on the Company&#146;s current report on Form 8-K dated November&nbsp;9, 2004 and
incorporated herein by reference.&#160; The
Company and ATS amended the Agreement again on December&nbsp;2, 2004 and the
amendment was filed as Exhibit 2.1 on the Company&#146;s current report on Form 8-K
dated December&nbsp;3, 2004 and incorporated herein by reference.&#160; The purchase price paid by the Company to ATS
was $131.2 million.</font></p>

floor plan agreements for truck inventory and the issuance of long-term debt to
finance the real estate acquired.</font></p>

AMERICAN TRUCK SOURCE, INC.</font></b></h1>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">SAN ANTONIO &#150; January&nbsp;4, 2005</font></b>
&#150; Rush Enterprises, Inc. (NASDAQ: RUSHA &amp; RUSHB), whose operations include
the largest network of Peterbilt heavy-duty truck dealerships in North America
and a John Deere construction equipment dealership in Texas, today announced
that it has successfully completed the acquisition of substantially all of the
assets American Truck Source, Inc.&#146;s (ATS), a Peterbilt truck dealer, Texas and
Tennessee operations for a total purchase price of $131.2 million.&#160; The acquisition provides Rush with rights to
sell Peterbilt trucks and parts from five new locations in Dallas, Fort Worth,
Abilene and Tyler, Texas, and Nashville, Tennessee.&#160; The acquisition expands the Company&#146;s
presence in the southern United States and results in the Company operating 43
dealerships in nine states.</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Company intends to integrate its new operations
into the Rush Truck Center system immediately.&#160;
Rush had unaudited revenues of $794.0 million and unaudited pre-tax
income from continuing operations of $19.9 million, for the first nine months
of 2004, while ATS&#146;s Texas and Tennessee operations had unaudited revenues of
$247.6 million and unaudited pre-tax income of $7.9 million for the same
period.&#160; The transaction was financed
through a combination of proceeds from a recent stock offering, expansion of
the company&#146;s existing floor plan agreement for truck inventory and the
issuance of long-term debt to finance real estate.&#160; In addition, the Company assumed liabilities
of approximately $2.8 million.&#160; The
Company expects the transaction to be accretive to future earnings.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">W. Marvin Rush, Chairman and Chief Executive Officer
of Rush Enterprises said, &#147;We are thrilled to announce the largest acquisition
in the 39 year history of our Company.&#160;
With ATS being one of the largest providers of owner-operator trucks in
the United States and estimates from industry analysts, manufacturers and
component suppliers for the demand for heavy-duty trucks to continue to
increase, this is the most important acquisition in the Company&#146;s history.&#160; The acquisition expands the Rush economic and
geographic footprint dramatically.&#160; This
enhanced market presence means that customers traveling the southern states will
be able to locate a Rush Truck Center all along their route.&#160; Our new Nashville location further expands
our southeastern presence and demonstrates our commitment to this region of the
country.&#148; &#160;Mr. Rush added, &#147;We look
forward to joining forces with a very well-run organization which was awarded
American Truck Dealer of the Year in 1996, includes franchises named North
American Dealer of the Year in 1999 and 2002 by Peterbilt, and has consistently
received Standard of Excellence and Platinum Oval awards from Peterbilt over
the years.&#148;</font></p>
