                                SUPPORT AGREEMENT

          THIS SUPPORT AGREEMENT ("Agreement") is executed as of this 18th day
of June, 1996 by United Auto Group, Inc., a Delaware corporation ("UAG") in
favor of Atlantic Auto Second Funding Corporation, a Delaware corporation
("AFC") (AFC and its respective successors and assigns are referred to herein as
the "AFC Parties").

                             PRELIMINARY STATEMENTS

          1.   AFC and Atlantic Auto Finance Corporation, a Delaware corporation
("Atlantic") have executed that certain Purchase Agreement of even date herewith
(the "AAFC Purchase Agreement") pursuant to which AFC may, from time to time,
purchase Receivables from Atlantic;

          2.   Atlantic is a subsidiary of UAG; and

          3.   It is a condition precedent to the initial Purchase by AFC under
the AAFC Purchase Agreement that UAG execute this Agreement and deliver it to
AFC.

          4.   It is intended by the parties hereto that this Agreement not
create any recourse against Atlantic or UAG for the payment of any uncollectible
Receivable.

          In consideration of the execution of the AAFC Purchase Agreement by
AFC, and for other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged by UAG, UAG agrees as follows:

                                   ARTICLE I.

                                   DEFINITIONS

          Section 1.1.   DEFINITIONS.  Unless otherwise defined in this
Agreement, all defined terms used in this Agreement, including the Preliminary
statements hereof, shall have the meaning ascribed to such terms in the AAFC
Purchase Agreement.

                                   ARTICLE II

                         PERFORMANCE SUPPORT OBLIGATION

          Section 2.1    PERFORMANCE SUPPORT OBLIGATION.  UAG hereby
unconditionally and irrevocably guarantees for the benefit of each of the AFC
Parties, the due and punctual performance, observance and payment by Atlantic
and its respective successors and assigns of all of the terms, covenants,
conditions,





agreements, undertakings and obligations on the part of Atlantic (whether
individually or as Servicer or otherwise) to be paid, performed or observed
under Sections 2.3, 2.4., 2.6, 2.7, 2.9 and 3.2 and Articles V (other than
Sections 5.1(e)) and VI of the AAFC Purchase Agreement and Sections 2.2, 2.5,
2.8 (other than Section 2.8(b)), 2.10, 2.11, 5.3 (other than Section 5.3(i)) and
5.4 and Article VI of the Transfer and Administration Agreement (all such terms,
covenants, conditions, agreements, undertakings and obligations on the part of
Atlantic to be paid, performed or observed being collectively called the
"Atlantic Obligations"); PROVIDED, HOWEVER, for  purposes of this Agreement, the
"Atlantic Obligations" shall not include (a) any obligation of Atlantic under
Sections 3.2 and 2.6(b) of the AAFC Purchase Agreement to repurchase any
Receivable if the request to make such repurchase occurs more than 12 months
after the breach of a representation and warranty as described in Section 3.2 or
after the failure to deliver the Custodian Confirmation as described in Section
2.6(b), as the case may be, except there shall be no such time limit applicable
with respect to any breach of the representation and warranty contained in
Section 3.2(c) and (d) of the AAFC Purchase Agreement, (b) Atlantic's
obligations to repurchase any Receivable under Section 2.7(ii) of the AAFC
Purchase Agreement, (c) any obligation of Atlantic under Section 6.1(f) of the
AAFC Purchase Agreement to provide indemnification for its failure to perform in
accordance with any provision of the AAFC Purchase Agreement or any agreement
contemplated by the AAFC Purchase Agreement other than the provisions contained
in those Sections of the AAFC Purchase Agreement and the Transfer and
Administration Agreement enumerated above in this sentence and (d) any
obligation of Atlantic under Section 6.2 or 6.3 of the AAFC Purchase Agreement
to provide indemnification to any entity other than the Buyer, Morgan Guaranty
Trust Company of New York, any Affiliate of Morgan Guaranty Trust Company of New
York and the officers, directors and agents of any of the foregoing.  In the
event that Atlantic shall fail in any manner whatsoever to perform, observe, or
pay any of the Atlantic Obligations when the same shall be required to be
performed, observed or paid, then UAG will itself duly and punctually perform,
observe and pay, or cause to be duly and punctually performed, observed or paid
the Atlantic Obligations, and it shall not be a condition to the accrual of the
obligation of UAG hereunder to perform, observe or pay any Atlantic Obligation
(or to cause the same to be performed, observed or paid) that any AFC Party
shall have first made any request of or demand upon or given any notice to UAG
or to Atlantic or its respective successors and assigns or have initiated any
action or proceeding against UAG or Atlantic or any of their respective
successors and assigns in respect thereof.  Any AFC Party may proceed to enforce
the obligations of UAG under this Section 2.1 without first pursuing or
exhausting any right or remedy which any AFC Party may have against Atlantic,
any other Person, the Purchased Receivables or any other property.  Each AFC
Party hereby acknowledges that the Atlantic Obligations do not (i) include any
obligations of Atlantic to repurchase the Receivables acquired by AFC under the
AAFC Purchase Agreement,


                                       -2-




except as described in Sections 2.6, 2.7 or 3.2 of the AAFC Purchase Agreement
or (ii) create recourse against Atlantic or UAG for the payment of any
uncollectible Receivable.

                                  ARTICLE III.

rights and remedies been permitted to be exercised.

          Section 5.2.   IRREVOCABILITY.  UAG agrees that its obligations under
this Agreement shall be irrevocable.  In the event that under applicable law
(notwithstanding UAG's agreement regarding the irrevocable nature of its
obligations hereunder), UAG shall have the right to revoke this Agreement, this
Agreement shall continue in full force and effect until a written revocation
hereof specifically referring hereto, signed by UAG is actually received by AFC

not relying on the AFC Parties to provide such information either now or in the
future.

rights at any time prior to the occurrence of the events described in the
preceding sentence, each and every amount so paid will be held in trust for the
benefit of the AFC Parties and forthwith be paid to AFC to be credited and
