                                                          Shares of Common Stock


                             UNITED AUTO GROUP, INC.

                          COMMON STOCK PURCHASE OPTION

                            Void after         , 2001

     United Auto Group, Inc., a Delaware corporation (the "Company"), hereby
certifies that, for value received, _________________, or their heirs,
representatives, successors and assigns, is entitled, subject to the terms set
forth below, to purchase from the Company at any time or from time to time after
the Initial Exercise Date (as defined below) and before 5:00 P.M. New York time,
on          , 2001 (the "Expiration Date") ________ fully paid and nonassessable
shares of Common Stock of the Company.  The purchase price per share of such
Common Stock ("the Exercise Price") shall be $__________ [equal to the initial
price to public of the Company's Common Stock specified in the final prospectus
with respect to the Company's initial public offering].

     1.  DEFINITIONS.  As used herein the following terms, unless the context
otherwise requires, have the following respective meanings:

          1.1.  The term "Company" includes any corporation which shall succeed
to or assume the obligations of the Company hereunder.

          1.2.  The term "Common Stock" shall mean the Common Stock of the
Company, and any other securities or property of the Company or of any other
person


(corporate or otherwise) which the holder of this Option at any time shall be
entitled to receive on the exercise hereof, in lieu of or in addition to Common
Stock, or which at any time shall be issuable in exchange for or in replacement
of Common Stock.

          1.3.  The term Current Fair Market Value of the Common Stock shall
mean with respect to each share of Common Stock:

               (a) if the Common Stock is traded on a securities exchange, the
fair market value shall be deemed to be the average of the closing prices over a
twenty-one (21) day period ending three days before the day with respect to
which the current fair market value of the Common Stock is being determined (or
such shorter period as the Common Stock may have been trading on such securities
exchange);

               (b) if the Common Stock is actively traded over-the-counter, the
fair market value shall be deemed to be the average of the closing bid and asked
prices quoted on the Nasdaq system (or similar system) over the twenty-one (21)
day period ending three days before the day with respect to the current fair
market value of the Common Stock is being determined (or such shorter period as
the Common Stock may have been quoted on such system); or

               (c) if at any time the Common Stock is not listed on any
securities exchange or quoted in the Nasdaq System or the over-the-counter
market, the current fair market value of Common Stock shall be the highest price
per share which the Company could obtain from a willing buyer (not a current
employee or director) for shares of Common Stock sold by the Company, from
authorized but unissued shares, as determined in good faith by its Board of
Directors, unless the Company shall become subject to a merger, acquisition or
other consolidation pursuant to which the Company is not the surviving party, in
which case the fair market value of Common Stock shall be deemed to be the value
received by the holders of the Company's Common Stock on a common equivalent
basis pursuant to such merger or acquisition.

     2.  INITIAL EXERCISE DATE; EXPIRATION.  This Option may be exercised at any
time or from time to time following             , 1996.  It shall expire at 5:00
P.M., New York time, on           , 2001.


                                       -2-


     3.  EXERCISE OF OPTION; PARTIAL EXERCISE.  This Option may be exercised in
full or in part by the holder hereof by surrender of this Option, with the form
of subscription attached hereto duly executed by such holder, to the Company at
its principal office, accompanied by payment of the Exercise Price of the shares
of Common Stock to be purchased hereunder.  For any partial exercise hereof, the
holder shall designate in the subscription the number of shares of Common Stock
that it wishes to purchase.  On any such partial exercise, the Company at its
expense shall forthwith issue and deliver to the holder hereof a new option of
like tenor, in the name of the holder hereof, which shall be exercisable for
such number of shares of Common Stock represented by this Option which have not
been purchased upon such exercise.

     The Exercise Price may be paid at the holder's election either by cash or
check payable to the order of the Company or by wire transfer.

     4.  WHEN EXERCISE EFFECTIVE.  The exercise of this Option shall be deemed
to have been effected immediately prior to the close of business on the business
day on which this Option is surrendered to the Company as provided in Section 2,
and at such time the person in whose name any certificate for shares of Common
Stock shall be issuable upon such exercise, as provided in Section 4, shall be
deemed to be the record holder of such Common Stock for all purposes.

     5.  DELIVERY ON EXERCISE.  As soon as practicable after the exercise of
this Option in full or in part, and in any event within five (5) business days
thereafter, the Company at its expense (including the payment by it of any
applicable issue taxes) will cause to be issued in the name of and delivered to
the holder hereof, or as such holder may direct, a certificate or certificates
for the number of fully paid and nonassessable full shares of Common Stock to
which such holder shall be entitled on such exercise.

     6.  ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES.  The character of
the shares of Common Stock issuable upon exercise of this Option (or any shares
of stock or other securities at the time issuable upon exercise of this Option)
and the purchase price therefor, are subject to adjustment upon the occurrence
of the following events:


                                       -3-


          6.1.  ADJUSTMENT FOR STOCK SPLITS, STOCK DIVIDENDS, RECAPITALIZATIONS,
     ETC.  The exercise price of this Option and the number of shares of Common
     Stock issuable upon exercise of this Option (or any shares of stock or
     other securities at the time issuable upon exercise of this Option) shall
     be appropriately adjusted to reflect any stock dividend, stock split,
     combination of shares, reclassification, recapitalization or other similar
     event affecting the number of outstanding shares of Common Stock (or such
     other stock or securities).  For example if there should be a two-for-one
     (2-for-1) stock split, the exercise price would be divided by two (2) and
     such number of shares would be doubled or if there should be a one-for-two
     (1-for-2) reverse stock split, the exercise price would be doubled and the
     number of shares would be divided by two (2).

          6.2.  ADJUSTMENT FOR OTHER DIVIDENDS AND DISTRIBUTIONS.  In case the
     Company shall make or issue, or shall fix a record date for the
     determination of eligible holders entitled to receive, a dividend or other
     distribution with respect to the Common Stock (or any shares of stock or
     other securities at the time issuable upon exercise of the Option) payable
     in (i) securities of the Company (other than shares of Common Stock) or
     (ii) assets (excluding cash dividends paid or payable solely out of
     retained earnings), then in each case, the holder of this Option on
     exercise hereof at any time after the consummation, effective date or
     record date of such event, shall receive, in addition to the Common Stock
     (or such other stock or securities) issuable on such exercise prior to such
     date, the securities or such other assets of the Company to which such
     holder would have been entitled upon such date if such holder had exercised
     this Option immediately prior thereto (all subject to further adjustment as
     provided in this Option).

          6.3.  ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.  In
     case of any consolidation or merger of the Company with or into any other
     corporation, entity or person, or any other corporate reorganization, in
     which the Company shall not be the continuing or surviving


                                       -4-


     entity of such consolidation, merger or reorganization, or any transactions
     in which in excess of fifty percent (50%) of the Company's voting power is
     transferred, or any sale of all or substantially all of the assets of the
     Company (any such transaction being hereinafter referred to as a
     "Reorganization"), then, in each case, the holder of this Option, on
     exercise hereof at any time after the consummation or effective date of
     such Reorganization (the "Effective Date"), shall receive, in lieu of the
     Common Stock issuable on such exercise prior to the Effective Date, the
     stock and other securities and property (including cash) to which such
     holder would have been entitled upon the Effective Date if such holder had
     exercised this Option immediately prior thereto (all subject to further
     adjustment as provided in this Option).

          6.4.  ADJUSTMENT FOR ISSUANCE OF RIGHTS OR OPTIONS.  In case the
     Company shall issue rights or options to all holders of its Common Stock
     entitling them to subscribe for or purchase shares of Common Stock (or
     securities convertible into Common Stock) at a price (or having a
     conversion price per share) less than the Current Fair Market Value of the
     Common Stock on the record date mentioned below, the Exercise Price shall
     be adjusted so that the same shall equal the price determined by
     multiplying the Exercise Price in effect immediately prior to the date of
     such issuance by a fraction, the numerator of which shall be the sum of the
     number of shares of Common Stock outstanding on the record date mentioned
     below and the number of additional shares of Common Stock that the
     aggregate offering price of the total number of shares of Common Stock so
     offered (or the aggregate conversion price of the convertible securities so
     offered) would purchase at the then current fair market value per share of
     the Common Stock, and the denominator of which shall be the sum of the
     number of shares of Common Stock outstanding on such record date and the
     number of additional shares of Common Stock offered for subscription or
     purchases (or into which the convertible securities so offered are
     convertible).  Such adjustment shall be made successively whenever such
     rights or options are issued and shall


                                       -5-


     become effective immediately after the record date for the determination of
     shareholders entitled to receive such rights or options; and, to the extent
     that shares of Common Stock are not delivered (or securities convertible
     into Common Stock are not delivered) after the expiration of such rights or
     options, the Exercise Price shall be readjusted to the Exercise Price that
     would then be in effect had the adjustment made upon the issuance of such
     rights or options been made upon the basis of delivery of only the number
     of shares of Common Stock (or securities convertible into Common Stock)
     actually delivered.

          6.5.  CERTIFICATE AS TO ADJUSTMENTS.  In case of any adjustment or
     readjustment in the price or kind of securities issuable on the exercise of
     this Option, the Company will promptly give written notice thereof to the
     holder of this Option in the form of a certificate, certified and confirmed
     by the Board of Directors of the Company, setting forth such adjustment or
     readjustment and showing in reasonable detail the facts upon which such
     adjustment or readjustment is based.

     7.  NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Option, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the holder of this
Option against dilution or other impairment.  Without limiting the generality of
the foregoing, the Company (a) will not increase the par value of any shares of
stock receivable on the exercise of this Option above the amount payable
therefor on such exercise, (b) will at all times reserve and keep available a
number of its authorized shares of Common Stock, free from all preemptive rights
therein, which will be sufficient to permit the exercise of this Option, and (c)
shall take all such action as may be necessary or appropriate in order that all
shares of Common Stock as may be issued pursuant to the exercise of this Option
will, upon issuance, be duly and validly issued, fully paid and nonassessable
and free from all


                                       -6-


taxes, liens and charges with respect to the issue thereof.

          8.  NOTICE OF RECORD DATE, ETC.  In the event of

               (a)  any taking by the Company of a record of the holders of any
class of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

               (b)  any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company, or any
transfer of all or substantially all the assets of the Company to or
consolidation or merger of the Company with or into any other person, or

               (c)  any voluntary or involuntary dissolution, liquidation or
winding up of the Company, or

               (d)  any proposed issue or grant by the Company of any shares of
stock of any class or any other securities, or any right or option to subscribed
for, purchase or otherwise acquire any shares of stock of any class or any other
securities, then and in each such event the Company will mail to the holder
hereof a notice specifying (i) the date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and stating the amount
and character of such dividend, distribution or right, (ii) the date on which
any such reorganization, reclassification, recapitalization, transfer,
consolidation, merger, dissolution, liquidation or winding-up is to take place,
and the time, if any is to be fixed, as to which the holders of record of Common
Stock (or any shares of stock or other securities at the time issuable upon the
exercise of this Option) shall be entitled to exchange their shares for
securities or other property deliverable on which reorganization,
reclassification, recapitalization, transfer, consolidation, merger,
dissolution, liquidation or winding-up, and (iii) the amount and character of
any stock or other securities, or rights or options with respect thereto,
proposed to be issued or granted, the date of such proposed issue or grant


                                       -7-


and the persons or class of persons to whom such proposed issue or grant is to
be offered or made. Such notice shall be mailed at least twenty (20) days prior
to the date therein specified.

     9.  EXCHANGE OF OPTIONS.  On surrender for exchange of this Option,
properly endorsed, to the Company, the Company at its expense will issue and
deliver to or on the order of the holder thereof a new Option of like tenor, in
the name of such holder or as such holder may direct, calling in the aggregate
on the face thereof for the number of shares of Common Stock called for on the
face of the Option so surrendered.

     10.  REPLACEMENT OF OPTIONS.  On receipt by the Company of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Option and, in the case of any such loss, theft or
destruction of this Option, on delivery of an indemnity agreement reasonably
satisfactory in form and amount of the Company or, in the case of any such
mutilation, on surrender and cancellation of such Option, the Company at its
expense will execute and deliver, in lieu thereof, a new Option of like tenor.

     11.  REGISTRATION RIGHTS.  The holder of this Option is entitled to all of
the benefits of the Registration Rights Agreement dated __________, 1996, by and
among UAG, Samuel X. DiFeo and Joseph DiFeo, as if such holder was a party to
such agreement.

     12.  INVESTMENT INTENT.  Unless a current registration statement under the
Securities Act of 1933, as amended, shall be in effect with respect to the
securities to be issued upon exercise of this Option, the holder thereof, by
accepting this Option, covenants and agrees that, at the time of exercise
hereof, and at the time of any proposed transfer of securities acquired upon
exercise hereof, such holder will deliver to the Company a written statement
that the securities acquired by the holder upon exercise hereof are for the own
account of the holder for investment and are not acquired with a view to, or for
sale in connection with, any distribution thereof (or any portion hereof) and
with no present intention (at any such time) of offering and distributing such
securities (or any portion thereof).

     13.  TRANSFER.  Subject to the transfer conditions referred to in the
legend endorsed hereon, this Option and all rights hereunder are transferrable,


                                       -8-


in whole or in part, without charge to the holder thereof upon surrender of this
Option with a properly executed assignment (in the form annexed hereto) at the
principal office of the Company.  Upon any partial transfer, the Company will at
its expense issue and deliver to the holder hereof a new Option of like tenor,
in the name of the holder hereof, which shall be exercisable for such number of
shares of Common Stock which were not so transferred.

     14.  NO RIGHTS OR LIABILITY AS A STOCKHOLDER.  This Option does not entitle
the holder hereof to any voting rights or other rights as a stockholder of the
Company.  No provisions hereof, in the absence of affirmative action by the
holder hereof to purchase Common Stock, and no enumeration herein of the rights
or privileges of the holder hereof shall give rise to any liability of such
holder as a stockholder of the Company.

     15.  DAMAGES.  The Company recognizes and agrees that the holder hereof
will not have an adequate remedy if the Company fails to comply with the terms
of this Option and that damages will not be readily ascertainable, and the
Company expressly agrees that, in the event of such failure, it shall not oppose
an application by the holder of this Option or any other person entitled to the
benefits of this Option requiring specific performance of any and all provisions
hereof or enjoining the Company from continuing to commit any such breach of the
terms hereof.

     16.  NOTICES.  All notices referred to in this Option shall be in writing
and shall be delivered personally or by certified or registered mail, return
receipt requested, postage prepaid and will be deemed to have been given when so
delivered or mailed (i) to the Company, at its principal executive offices and
(ii) to the holder of this Option, at such holder's address as it appears in the
records of the Company (unless otherwise indicated by such holder).

     17.  PAYMENT OF TAXES.  All shares of Common Stock issued upon the exercise
of this Option shall be validly issued, fully paid and nonassessable, and the
Company shall pay all taxes and other governmental charges that may be imposed
in respect to the issue or delivery thereof.


                                       -9-


     18.  MISCELLANEOUS.  This Option and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought.  This Option is being delivered in the State of New York and shall be
governed by and construed and enforced in accordance with the internal laws of
the State of New York (without reference to any principles of the conflicts of
laws).  The headings in this Option are for purposes of reference only, and
shall not limit or otherwise affect any of the terms hereof.
