      a member of all committees thereof (including the Executive Committee),
      and as an officer, employee, director and committee member of any and all
      subsidiaries and affiliates of the Company will also be effective as of
      April 17, 1997 (except for your resignation as a director of Foamex
      International Inc., which will be effective as of the date hereof), and

      to be provided to you under your Employment Agreement, dated as of June
      21, 1996 (your "Employment Agreement"): (i) on April 1, 1997, a bonus in
      the amount of $375,000 and, on your Termination Date, base salary earned
      as of your Termination Date and not yet paid, (ii) a monthly payment,
      payable in accordance with the Company's normal pay practices, for the

      (iii) on your Termination Date, full title in the Company automobile
      currently being used by you, (iv) an unaccountable monthly allowance
      through December 31, 2000, payable at the time of each payment under
      subclause (ii) above, in the amount of $8,333; (v) continued
      participation in the Company's life insurance plan, on the same basis as
      for other Company employees, in accordance with the terms and conditions
      of such plan and to the extent such coverage is not prevented by
      applicable law or regulation and continued reimbursement for your
      coverage under your prior employer's medical and dental plans on a "tax
      grossed-up basis"; provided, however, that such participation and
      reimbursement will cease on the earlier of (A) December 31, 2000, and (B)
      the date or dates you receive similar coverage and benefits under the
      plans and programs of a subsequent employer (such coverage and benefits
      to be determined on a coverage-by-coverage, or benefit-by-benefit,
      basis); (vi) the accelerated vesting of all unvested stock options, and
      the grant of options (as described more fully in clause 4 below) and
      (vii) all reasonable attorney's fees and expenses (not to exceed $18,000)
      incurred by you in connection with the negotiation of this letter.

4.    Subject to your execution and delivery on March 14, 1997 of your
      irrevocable written confirmation that the seven day revocation period
      referenced in clause 13 below has expired and that you have elected not
      to revoke the agreement set forth herein, (i) the Company confirms that
      the Stock Option Committee of the Company's Board of Directors has
      granted you an option under the Company's Stock Option Plan to purchase
      up to 100,000 shares of the Company's common stock at an exercise price
      equal to the reported closing price of such common stock on April 16,
      1997 on the New York Stock Exchange, which option shall be fully vested
      and exercisable from April 17, 1997 and shall have the terms and
      conditions set forth in the Stock Option Agreement attached hereto as
      Exhibit B and (ii) notwithstanding any prior agreements to the contrary,
      all options previously granted to you and referenced



Mr. Carl Spielvogel
March 7, 1997
Page 3


      in Section 3.1(c) of your Employment Agreement will, as previously
      contemplated, be fully vested and exercisable from April 17, 1997 through
      and including April 17, 2001. To the extent any such options have not
      been exercised on or prior to April 17, 2001, they will be immediately
      forfeited. To the extent the issuance of shares upon exercise of any of
      the options referred to in this clause 4 is not currently registered
      under the Securities Act of 1933, the Company will file a registration
      statement on Form S-8 on or before April 30, 1997 covering such issuance
      and shall use its best efforts to keep all such registrations effective
      until April 17, 2001. It is understood that the Stockholders Agreement
      referred to in Section 3.1(c)(iv) of your Employment Agreement is no
      longer in effect. The Company shall use commercially reasonable efforts
      to obtain from J.P. Morgan Securities Inc. a release from the 180-day
      lock-up agreement as of April 17, 1997, for the 26,118 shares owned by
      you and the shares issuable upon exercise of your options.

5.    The provisions of Section 4.3(a) of your Employment Agreement (regarding
      confidentiality) shall survive the execution of this letter agreement and
      continue, without time limitation. Additionally, the provisions of
      Section 4.3(b) of your Employment Agreement (regarding non-competition)
      shall survive the execution of this letter agreement, and continue
      through April 16, 1998. You agree that the Company will suffer
      irreparable damage if the terms of any such provisions are breached and,
      in addition to all other remedies available to the Company, that the
      Company will be entitled as a matter of right to injunctive relief in
      respect of any such breach.

6.    The provisions of Sections 6.1, 6.2, 6.5 and 6.8 of your Employment
      Agreement will also survive the execution of this letter agreement.

7.    You affirm that you will not make any statements at any time that
      disparage the reputation of the Company or any of its affiliates, or any
      officers, directors, employees or agents of the Company or any of its
      affiliates, or, until December 31, 2000, any automobile dealers or
      manufacturers. The Company, on behalf of itself and its executive
      officers, agrees that it will not make any statements at any time that
      disparage your reputation.

8.    The form of press release confirming your resignation described in
      clauses 1 and 2 herein shall be subject



Mr. Carl Spielvogel
March 7, 1997
Page 4


      to our mutual agreement. Any statements by the Company or you to third
      parties or to employees of the Company regarding the termination of your
      employment shall be consistent with such press release or subject to our
      mutual agreement.

9.    For the period commencing on your Termination Date and ending on December
      31, 2000, subject to your other personal and business commitments, you
      agree to provide such consulting services at mutually convenient times
      and places as the Company may reasonably request, which requests shall be
      consistent with your knowledge and responsibilities as former Chief
      Executive Officer and Chairman of the Board of Directors of the Company.
      Notwithstanding anything to the contrary in this letter, but without
      limiting any other remedies available to the Company, a breach of this
      clause 9 will not entitle the Company to withhold payments set forth in
      clauses 3(ii) and (iv) or to offset any alleged damages for such breaches
      against such payments.

10.   In consideration for the payments set forth in this letter, you and your
      heirs, executors, administrators, legal representatives, agents,
      successors in interest and assigns, hereby knowingly and voluntarily
      waive and unconditionally release and forever discharge, as of the date
      hereof and as of your Termination Date, from all or any manner of
      actions, causes and causes of actions, suits, debts, obligations,
      damages, complaints, liabilities, losses, covenants, contracts,
      controversies, agreements, promises, variances, trespasses, judgments,
      and expenses (including attorneys' fees and costs), executions, claims
      and demands whatsoever at law or in equity which you ever had, now have,
      or which you hereafter can, shall or may have against the Company on or
      prior to the date of this letter and your Termination Date, as the case
      may be. This release and waiver includes but is not limited to any rights
      or claims under United States federal, state or local law and the
      national or local law of any foreign country (statutory or decisional),
      for payments due or benefits required to be provided under your
      Employment Agreement, for wrongful or abusive discharge, for breach of
      your Employment Agreement or any other contract, or for discrimination
      based upon race, color, ethnicity, sex, age, national origin, religion,
      disability, sexual orientation, or any other unlawful criterion or
      circumstance, including rights or claims under the Age Discrimination in
      Employment Act of 1967, as amended. In this clause 10, the word "Company"
      means United

      (and their affiliates), representatives and agents, past or present, and
      any person or entity which may succeed to the rights and liabilities of
      any such entities or persons by assignment or otherwise. Notwithstanding
      the foregoing, nothing in this clause 10 shall be deemed to release or
      waive any obligations of the Company under this letter, your stock option
      agreements or the Registration Rights Agreement, dated October 15, 1993,
      as amended (collectively, the "Agreements").

      to revoke the agreement set forth herein, in consideration for your
      covenants in this letter, the Company hereby unconditionally releases and

      Date, you from all or any manner of actions, causes and causes of
      actions, suits, debts, obligations, damages, complaints, liabilities,
      losses, covenants, contracts, controversies, agreements, promises,
      variances, trespasses, judgments, and expenses (including attorneys' fees
      and costs), executions, claims and demands whatsoever at law or in equity
      which the Company ever had, now has, or which the Company hereafter can,
      shall or may have on or prior to the date of this letter and your
      Termination Date, as the case may be. Notwithstanding the foregoing,
      nothing in this clause 11 shall be deemed to release or discharge any of
      your obligations under any of the Agreements.

12.   You affirm that, prior to the execution of this letter, you have
      consulted with an attorney concerning the terms and conditions set forth
      herein, and that you have been given up to 21 days to consider signing
      this letter.

13.   For a period of seven days following your signing of this letter, you may
      revoke and cancel the agreement set forth herein.

14.   You will be under no obligation to seek other employment and there shall
      be no offset against amounts due you under this letter on account of any
      remuneration attributable to any subsequent employment that you may

      hereby agree to inform the Company upon your participation in employee
      benefit plans or programs of a subsequent employer which provide medical,
      dental, hospitalization or life insurance coverage by such subsequent
      employer to the extent you are provided with coverage and benefits
      similar to those you are receiving from the Company.

15.   You agree, for so long as this letter agreement is otherwise
      confidential, that you will not disclose the fact of this letter or any
      of its terms or provisions to any person without the prior written

      shall prohibit disclosure of such information to the extent required by
      law, nor prohibit disclosure by you to any legal or financial consultant,
      member of your immediate family or prospective employer, if such person
      first agrees to be bound by the confidentiality provisions of this clause
      15. It is acknowledged that this letter will be filed by the Company with
      the Securities and Exchange Commission pursuant to applicable law.

16.   This letter may be executed in any number of counterparts, each of which
      when so executed and delivered shall constitute an original and which all

      letter, or the application thereof, shall, to any extent, be invalid or
      unenforceable, the remaining terms and provisions of this letter or the
      application thereof shall not be invalidated thereby, and each term and
      provision hereof shall be construed with all other remaining terms and
      provisions hereof to effect the intent of the Company and you to the
      fullest extent permitted by law. In the event clause 10 shall be invalid
      or unenforceable, then this entire agreement shall become null and void
      and any payments of any kind made to you hereunder shall be returned.

19.   This letter may not be amended, waived or modified, in whole or in part,
      except by a writing signed by each of you and the Company.

20.   Except for clause 10 herein, nothing herein expressed or implied is

      entity (other than you or your beneficiaries and the Company) any rights
      or remedies under or by reason of this letter.

21.   You understand that nothing contained in this letter shall be deemed or
      construed as an admission of wrongdoing or liability on your part or on
      the part of the Company.

22.   This letter (including the provisions of your Employment Agreement
      explicitly incorporated by reference herein) and the other Agreements
      constitute the entire agreement between you and the Company and supersede

      be governed by, the laws of the State of New York without giving effect

      all taxes due thereon and (b) you shall furnish such form (but not your
      income tax return) reasonably requested by the Company to evidence such
      payment. You shall indemnify the Company from all taxes, interest,
      penalty or other loss (including reasonable attorneys' fees) arising from
      any failure by the Company to withhold any such payments.

                             STOCK OPTION AGREEMENT
                             ----------------------

         This Stock Option Agreement ("Agreement") is dated as of April 17,
1997, and is entered into between United Auto Group, Inc., a Delaware
corporation (the "Company"), and Carl Spielvogel ("Executive").

                              W I T N E S S E T H:

         WHEREAS, the Company is a party to an employment agreement with
Executive, dated as of June 21, 1996 (as amended, supplemented or otherwise
modified from time to time, the "Employment Agreement"); and

         WHEREAS, the Company is a party to a consulting agreement with
Executive, dated March 7, 1997 (the "Consulting Agreement"); and

         WHEREAS, pursuant to the Employment Agreement and Consulting
Agreement, the Company is granting the Executive options to purchase shares of
voting common stock, par value $0.0001 per share (the "Common Stock"), of the
Company, on the terms and conditions set forth herein and in the Employment and
Consulting Agreements.

         NOW, THEREFORE, the parties hereby agree:

         1. Grant of Options. The Company hereby grants to the Executive an
option (the "Option") to purchase, at the exercise price of $_____ per share,
100,000 shares of Common Stock.

         2. Exercisability of Options. The Option will be fully vested and
exercisable as of the date of this Agreement.

         3. Method of Exercising Options. (a) The Executive may exercise the
Option by delivering to the Company a written notice stating the number of
shares that the Executive has elected to purchase at that time from the Company
and full payment of the purchase price of the shares then to be purchased.
Payment of the purchase price of the shares may be made (i) by certified or
bank cashier's check payable to the order of the Company, or (ii) in the
discretion of the Board of Directors of the Company or duly authorized
committee thereof, by such other method as may be approved by such board or
committee from time to time.



            (b) At the time of exercise, the Executive shall pay to the Company
such amount as is necessary to satisfy the Company's obligation to withhold
Federal, state or local income or other taxes incurred by reason of the
exercise or the transfer of shares thereupon.

         4. Issuance of Shares. As promptly as practicable after receipt of
notification of exercise, full payment of purchase price and satisfaction of
tax withholding as provided in Section 3, the Company shall issue or transfer
to the Executive the number of shares as to which the Options have been so
exercised and shall deliver to the Executive a certificate or certificates
therefor, registered in his name.

         5. Terms and Conditions of Exercise. (i) The Option shall terminate on
April 17, 2001.

            (ii) The Option shall not be transferable, except by will or the
laws of descent and distribution, provided that Executive may at any time
transfer all or a portion of the Option to his spouse, any of his descendants
or trusts for the benefit of Executive, his spouse or his descendants, subject
to all of the terms and conditions of the Option.

            (iii) Whenever the word "Executive" is used in any provision of
this Agreement under circumstances where the provision should logically be
construed to apply to the executors, the administrators, personal
representatives, or the person or persons to whom the Option may be transferred
pursuant to clause (ii) of this Section 5, the word "Executive" shall be deemed
to include such person or persons.

         6. Rights as Stockholder. The Executive or a transferee of the Option
shall have no rights as a stockholder with respect to any shares of Common
Stock covered by the Option until he shall have become the holder of record of
such shares.

         7. Recapitalizations, Reorganizations, Etc. (a) The existence of the
Option shall not affect the power of the Company or its stockholders to
accomplish adjustments, recapitalizations, reorganizations or other changes in
the Company's capital structure or its business, or any merger or consolidation
of the Company, or any issue of stock or of options, warrants or rights to
purchase stock or securities ahead of or affecting any of the shares of Common
Stock or the rights thereof or convertible into or exchangeable for shares of
Common Stock, or the dissolution or liquidation of the Company, or any sale or
transfer of all or any part of its assets or business, or any other corporate
act.

            (b) Upon any change in the outstanding shares of Common Stock by
reason of any recapitalization, merger,

                                      -2-


consolidation, spin-off, combination or exchange of shares or other corporate
change, or any distributions to common shareholders other than ordinary cash
dividends, the Company shall make such substitutions or adjustments as are
appropriate and equitable, as to the number or kind of shares of Common Stock
or other securities covered by the Option and the exercise price thereof.

         8. Notice. Any notice required or permitted hereunder shall be in
writing and shall be sufficiently given if personally delivered or if sent by
telegram, telex, facsimile transmission or by registered or certified mail,
postage prepaid, with return receipt requested, as follows:
