CUSIP No. 909440109

PRELIMINARY NOTE:

     On February 22, 2002,  International  Motor Cars Group I, L.L.C. ("IMCG I")
and J.P. Morgan Partners (BHCA),  L.P. ("JPMP"),  Combined  Specialty  Insurance
Company  (formerly  known as Virginia  Surety  Company,  Inc.)  ("AON"),  Penske
Corporation,  and Penske Capital Partners,  L.L.C. (the "Managing  Member",  and
each of JPMP,  AON and Penske  Corporation,  an "IMCG I Member"),  being all the
members  of IMCG  I,  entered  into a  letter  agreement  (the  "IMCG  I  Letter
Agreement").  Under the terms of the IMCG I Letter Agreement, each IMCG I Member
may,  in  connection  with its  execution  of a cash  sale of shares of Series A
preferred  stock or common  stock of United  Auto  Group,  Inc.  (the  "Issuer")
attributable  to  its  membership  interest  in  IMCG  I,  require  that  IMCG I
distribute such shares to that IMCG I Member,  subject to certain conditions (an
"IMCG I  Member  Distribution").  Such  conditions  are as  follows:  (i)  until
February 22, 2003, no IMCG I Member may require IMCG I to distribute  any of the
shares of common  stock  obtained by IMCG I pursuant to its exercise of warrants
of the Issuer,  unless immediately after giving effect to such distribution,  no
other  shares of Series A preferred  stock,  Series B preferred  stock or common
stock of the Issuer are attributable to such IMCG I Member's membership interest
in IMCG I or, with  respect to JPMP,  IMCG II (as defined  below) and (ii) other
than  distributions  permitted by the IMCG I Letter  Agreement or in  connection
with  reallocation  of shares to the Managing  Member  permitted  under IMCG I's
operating agreement, IMCG I will not sell or otherwise transfer to a third party
any shares of the Issuer attributable to an IMCG I Member's membership interest,
without the prior written consent of such IMCG I Member. Moreover,  neither IMCG
I nor any IMCG I Member  can  cause  the  conversion  of any  shares of Series A
preferred stock  attributable to its membership  interest,  except in connection
with an IMCG I Member  Distribution  and upon  receipt  by IMCG I of  notice  of
redemption by the Issuer.  Notwithstanding  the foregoing,  the Managing  Member
shall  have the  right at any time to cause  IMCG I to  distribute  to an IMCG I
Member all or a portion of the shares of Series A preferred  stock and/or common
stock of the Issuer (or any proceeds of such shares) attributable to such IMCG I
Member's membership interest.

     On February 22, 2002, International Motor Cars Group II, L.L.C. ("IMCG II")
and JPMP and the Managing Member (each of JPMP and the Managing Member, an "IMCG
II Member"),  being all the members of IMCG II, entered into a letter  agreement
(the  "IMCG II  Letter  Agreement").  Under  the  terms  of the  IMCG II  Letter
Agreement,  each IMCG II Member may, in connection  with its execution of a cash
sale of shares of Series A preferred  stock,  Series B preferred stock or common
stock of the Issuer  attributable to its membership interest in IMCG II, require
that IMCG II distribute  such shares to that IMCG II Member,  subject to certain
conditions (an "IMCG II Member  Distribution").  Such conditions are as follows:
(i) until February 22, 2003, no IMCG II Member may require IMCG II to distribute
any of the shares of common  stock  obtained by IMCG II pursuant to its exercise
of  warrants of the  Issuer,  unless  immediately  after  giving  effect to such
distribution,  no other shares of Series A preferred  stock,  Series B preferred
stock or common  stock of the Issuer are  attributable  to such IMCG II Member's
membership  interest  in IMCG I or IMCG II and  (ii)  other  than  distributions
permitted by the IMCG II Letter Agreement or in connection with  reallocation of
shares to the Managing  Member  permitted  under IMCG II's operating  agreement,
IMCG II will not sell or  otherwise  transfer to a third party any shares of the
Issuer  attributable  to an IMCG II Member's  membership  interest,  without the
prior written consent of such IMCG II Member. Moreover,  neither IMCG II nor any
IMCG II Member  can cause the  conversion  of any  shares of Series A  preferred
stock or Series B preferred  stock of the Issuer  attributable to its membership
interest,  except in  connection  with an IMCG II Member  Distribution  and upon
receipt by IMCG II of notice of  redemption by the Issuer.  Notwithstanding  the
foregoing, the Managing Member shall have the right at any time to cause IMCG II
to  distribute  to an IMCG II Member  all or a portion of the shares of Series A
preferred stock,  Series B preferred stock and/or common stock of the Issuer (or
any proceeds of such shares)  attributable  to such IMCG II Member's  membership
interest.

     On May 2, 2002, in accordance  with the  Certificate  of Designation of the
Series A preferred stock of the Issuer, (i) IMCG I converted 5,450.106 shares of
Series A preferred stock owned of record by it and acquired direct  ownership of
the  5,570,160  shares of voting  common  stock of the  Issuer  (which  included
120,054  shares of voting  common  stock of the Issuer  received in lieu of cash
dividends  accrued on the outstanding  shares of Series A preferred stock during
the period from  December  31,  2001 to May 2, 2002) and (ii) IMCG II  converted
1,431.340  shares of Series A preferred stock owned of record by it and acquired
direct ownership of 1,462,869 shares of voting common stock of the Issuer (which
included  31,529 shares of voting common stock of the Issuer received in lieu of
cash dividends  accrued on the  outstanding  shares of Series A preferred  stock
during the period from December 31, 2001 to May 2, 2002).

     On August 3, 2002, in accordance with the Certificate of Designation of the
Series B preferred  stock of the Issuer,  IMCG II  converted  648.588  shares of
Series B preferred stock owned by record by it and acquired direct  ownership of
652,452 shares of non-voting common stock of the Issuer.

     As a result of the  conversions  of the  Series A  preferred  stock and the
Series  B  preferred  stock  by IMCG I and  IMCG II  respectively,  no  Series A
preferred stock or Series B preferred stock remains issued and outstanding.

     The  number  of  shares  reported  as  beneficially  owned  by JPMP in this
Schedule 13G represent the shares of the Issuer beneficially owned by JPMP as of
April 24,  2003 after  giving  effect to (i) the sale by JPMP of its  membership
interests in IMCG I to a  wholly-owned  subsidiary of Penske  Corporation (which
represents beneficial ownership of

1,614,708  shares of common stock of the Issuer) on April 15, 2003  (the "PENSKE
SALE"),  (ii) the  allocation  of 43,929 shares of common stock of the Issuer to
the carry  account of the Managing  Member in  connection  with the Penske Sale,
(iii) the sale of  1,291,766  shares of common  stock of the Issuer on April 24,
2003 to Mitsui & Co., Ltd. and the sale of 322,942 shares of common stock of the
Issuer  on April 24,  2003 to  Mitsui & Co.  (U.S.A.)  Inc.  (collectively,  the
"MITSUI SALE"),  and (iv) the allocation of 70,525 shares of common stock of the
Issuer to the carry account of the Managing Member in connection with the Mitsui
Sale. Pursuant to the respective operating agreements of each of IMCG I and IMCG
II,  the  number of  shares  of the  Issuer  attributable  to JPMP's  membership
interests  in IMCG I and IMCG II shall be  reduced at the time of each IMCG I or
IMCG II Member Distribution to JPMP by the number of shares actually distributed
to JPMP and by the  number of shares  attributable  to the carry  account of the
Managing  Member  of IMCG I or IMCG  II,  as the case  may be,  pursuant  to the
respective  operating  agreements  of each of IMCG I and IMCG II with respect to
the shares so  distributed  to JPMP.  JPMP has  withdrawn as a member of each of
IMCG I and IMCG II.
