     Re: Enforceability Opinion

     We are issuing  this opinion  letter in our capacity as special  counsel to
Capital Auto  Receivables,  Inc. (the  "Seller") and General  Motors  Acceptance
Corporation  ("GMAC")  in  connection  with the  issuance  of  $1,162,000,000.00
aggregate  principal  amount of Class A-1 Asset  Backed  Notes  (the  "Class A-1
Notes"),  $688,500,000.00  aggregate  principal amount of Class A-2 Asset Backed
Notes (the "Class A-2 Notes"),  $766,000,000.00  aggregate  principal  amount of
Class A-3 Asset Backed Notes (the "Class A-3 Notes") and $334,500,000  aggregate
principal  amount of Class A-4 Asset  Backed  Notes  (the  "Class A-4 Notes" and
together with the Class A-1 Notes,  the Class A-2 Notes and the Class A-3 Notes,
the  "Notes") by Capital  Auto  Receivables  Asset Trust  2002-3 (the  "Trust"),
pursuant  to an  Indenture  (the  "Indenture"),  between the Trust and Bank One,
National Association, as Indenture Trustee (the "Indenture Trustee").

     The  Trust  intends  to issue  the  Notes on or about  August  8, 2002 (the
"Issuance Date").

     We are  generally  familiar  with the  proceedings  required to be taken in
connection with the proposed authorization,  issuance and sale of the Notes, and
in order to express the opinion hereinafter stated, we have, among other things,
examined and relied, to the extent we deem proper, on the following documents:

               (i) the  registration  statement  filed with the  Securities  and
               Exchange Commission (the "Commission") pursuant to Rule 415 under
               the Securities  Act of 1933, as amended (the "Act"),  on Form S-3
               (File No.  333-75464)  on  January  28,  2002,  with  respect  to
               asset-backed  notes and certificates,  including the Notes, to be
               issued and sold in series from time to time, in the form in which
               it became effective, including the exhibits thereto;

               (ii)  form  of  prospectus   supplement  relating  to  the  Notes
               substantially  in  the  form  to be  filed  with  the  Commission
               pursuant  to  Rules  424(b)(5)  and  424(c)  under  the Act  (the
               "Prospectus Supplement") and the prospectus, dated July 29, 2002,
               relating thereto (the "Base  Prospectus"  and,  together with the
               Prospectus Supplement, the "Prospectus");

               (iii) the Trust Agreement (the "Original Trust Agreement"), dated
               as of July 26, 2002,  between the Seller and Deutsche  Bank Trust
               Company Delaware, as Owner Trustee, and a form of the Amended and
               Restated Trust Agreement (the "Trust Agreement");

               (iv) a form of the Trust Sale and Servicing  Agreement  among the
               Seller,  GMAC,  as  Servicer,  and the Trust (the "Trust Sale and
               Servicing Agreement");

               (v) a form of the Indenture;

               (vi) a form of the Pooling and Servicing  Agreement (the "Pooling
               and Servicing Agreement"), between GMAC and the Seller; and

               (vii) such other  documents as we have deemed  necessary  for the
               expression  of  the  opinions  contained  herein   (collectively,
               documents (iii) - (vi) are referred to herein as the "Transaction
               Documents").

     In our examination,  we have assumed that the Transaction Documents will be
executed in the form submitted to us. We have also assumed,  without independent
verification, that the facts and representations and warranties in the documents
upon  which  we  relied  are  true  and  correct,   and  that  the  transactions
contemplated  by such  documents  have been or will be  consummated  strictly in
accordance with their terms.

     On the basis of the  foregoing and on the basis of our  examination  of the
Seller's  Amended and  Restated  Certificate  of  Incorporation  and Amended and
Restated  By-laws and a review of a Certificate of the Secretary of State of the
State of Delaware as to the good standing of the Seller, it is our opinion that:

               (a) The  Seller is a  corporation  validly  existing  and in good
               standing under the laws of the State of Delaware.

               (a) With respect to the Notes of any series  issued by the Trust,
               when duly executed and  authenticated by the Indenture Trustee in
               accordance  with  the  terms of the  Indenture,  and  issued  and
               delivered against payment thereof,  the Notes will have been duly
               authorized  by all  necessary  action  of the Trust and will have
               been legally issued and will be  enforceable  in accordance  with
               their  terms and  entitled  to the  benefits  of the  Transaction
               Documents,  except as the same may be  limited by Title 11 of the
               United   States   Code   or   other    bankruptcy,    insolvency,
               reorganization,   moratorium,   or  other  laws  relating  to  or
               affecting the  enforcement of creditors'  rights or the relief of
               debtors,  as may be in effect  from time to time,  or by  general
               principles of equity.

     We do not  find  it  necessary  for  the  purposes  of  this  opinion,  and
accordingly we do not purport to cover herein,  the application of securities or
"Blue Sky" laws of the various states to the offer or sale of the Notes.

     We wish to advise  you that we are  members  of the bar of the State of New
York and the opinions  expressed  herein are limited to the laws of the State of
New York, the federal laws of the United States, the General  Corporation Law of
the State of Delaware and the Delaware Business Trust Act.

     We hereby consent to the filing of this opinion with Form 8-K in connection
with the sale of the Notes. In giving this consent, we do not thereby admit that
we come within the category of persons whose consent is required under Section 7
of the Securities Act of 1933, as amended,  or the rules and  regulations of the
Securities and Exchange Commission thereunder.

                                                     Sincerely,




                                                     KIRKLAND & ELLIS
