      RE:   SAM DIFEO COMPENSATION

Dear Paul:

      As you know, Sam DiFeo ("DiFeo") has for some time been serving as
President and Chief Operating Officer of United Auto Group, Inc. (the "Company")
pursuant to that certain letter agreement between the parties dated as of August
3, 1999. (the "Employment Agreement"). In this regard, the Agreement
contemplates that DiFeo's employment as President and Chief Operating Officer,
for which the Company has compensated DiFeo at the rate of $360,000 per annum,
would terminate upon the expiration of the extended term thereof (i.e., May 31,
2000), whereupon DiFeo would have the benefit of that certain Consulting
Agreement between the parties (the "Consulting Agreement").

      Without regard to the May 31, 2000 termination date set forth in the
Employment Agreement, DiFeo has, at the request of the Company, continued to
serve as President and Chief Operating Officer of the Company beyond said
termination date. The Company has now requested that DiFeo continue to serve in
such capacity for a further period of time. DiFeo is agreeable to such
continuation of his services and the parties have reached an agreement on the
terms and conditions of his continued service. The terms and conditions of
DiFeo's continued service for the Company are generally as follows:

   1. DiFeo will continue his service to the Company as President and Chief
      Operating Officer on a full-time basis through December 31, 2000 at an
      annual salary of $500,000, with the difference between DiFeo's
      compensation rate of $360,000 and the adjusted $500,000 to be payable to
      DiFeo in equal installments during the period June 1, 2000 through
      December 31, 2000 by additions to the periodic paychecks otherwise payable
      to him at the base compensation rate of $360,000.

   2. The Consulting Agreement shall be modified as required to provide that the
      term thereof shall be for the period January 1, 2001 through December 31,
      2002, with the

      Company to have the option to extend the term of the Consulting Agreement
      for an additional one year, through December 31, 2003. During the
      effective period of the Consulting Agreement as may be extended, DiFeo
      will perform services for the Company as more specifically provided for
      therein, and will be compensated for such services as set forth in the
      Consulting Agreement.

   3. Upon the expiration of the amended Consulting Agreement on December 31,
      2002, or December 31, 2003, in the event the term of the Consulting
      Agreement is extended as noted above, DiFeo shall have the benefit of a
      new consulting agreement (the "New Consulting Agreement"), which will
      provide that DiFeo will be available, as convenient to DiFeo, to consult
      with the Company for an additional period of two years at an annual
      compensation rate of $400,000.

   4. In connection with the revised employment and compensation status of DiFeo
      as set forth above, the consulting agreements previously in place between
      the Company and each of DiFeo's brother, Joseph DiFeo, and DiFeo's father,
      Samuel DiFeo, with annual compensation at the rate of $50,000, shall be
      continued and extended through December 31, 2002.

    If the above accurately sets forth your understanding of the agreement
reached between DiFeo and the Company relative to DiFeo's continued employment
by the Company, please evidence your understanding by signing this letter where
indicated below and returning same to me. As we discussed, 1 will thereupon
proceed to prepare the requisite documentation to effectuate the parties
agreement.

                                                        Sincerely yours,

PRELIMINARY STATEMENTS

     A. The Borrower, the

lenders party thereto and the Administrative Agent entered into a certain
Credit Agreement, dated as of October 24, 2002 (the “Credit Agreement”).
 All capitalized terms used herein without definition shall have the same meanings herein as

Agreement, and the Lenders are willing to do so under the terms

and conditions set forth in this
Amendment.

     Now, THEREFORE, for good and

including finance charges
related thereto, whether or not they have been earned by

performance, and all rights
in any merchandise or goods which any of the same may represent,

and all rights,
title, security, guaranties and related assets (including without

limitation, books

without limitation, any
right of stoppage in transit and all obligations and other

proceeds with respect to

Accounts Receivable

     “Receivables Facility

Attributed Indebtedness” means the amount of obligations
outstanding under a receivables purchase facility on any date of

determination that
