     Re: Federal Income Tax Consequences

     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:

(1)  the issuance of $680,000,000  aggregate principal amount of Class A-2 Asset
     Backed  Notes (the "Class A-2  Notes"),  $385,000,000  aggregate  principal
     amount  of  Class  A-3  Asset   Backed   Notes  (the  "Class  A-3  Notes"),
     $150,643,000  aggregate  principal  amount of Class A-4 Asset  Backed Notes
     (the "Class A-4 Notes" and together  with the Class A-2 Notes and the Class
     A-3 Notes,  the "Offered  Notes") by Capital Auto  Receivables  Asset Trust
     2001-2 (the "Trust"),  pursuant to an Indenture (the "Indenture"),  between
     the Trust and Bank One,  National  Association  as  Indenture  Trustee (the
     "Indenture Trustee"); and

(2)  the issuance of $64,566,572.92  aggregate  principal amount of Asset Backed
     Certificates  (the  "Certificates")  by  the  Trust,  pursuant  to a  Trust
     Agreement  (the "Trust  Agreement"),  between the Seller and Bankers  Trust
     (Delaware) as Owner Trustee (the "Owner Trustee"); and

(3)  the issuance of $447,000,000  aggregate principal amount of Class A-1 Asset
     Backed  Notes (the  "Class A-1 Notes") and the  Variable  Pay Asset  Backed
     Revolving Note,  Class 1 (the "Variable Pay Revolving  Note") in an initial
     aggregate principal amount of $425,000,000, pursuant to the Indenture.

The Offered  Notes,  the Class A-1 Notes and the Variable Pay Revolving Note are
sometimes  referred to collectively  herein as the "Notes." The Trust intends to
issue the Notes and the  Certificates  on or about June 26, 2001 (the  "Issuance
Date"). The Trust may issue additional Variable Pay Asset Backed Revolving Notes
after the Issuance  Date.  In arriving at the opinions  expressed  below,  among
other things,  we have examined and relied, to the extent we deem proper, on the
following documents:



Capital Auto Receivables, Inc.

          (i) a copy of 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.
     333-93431)  on March 22,  2001,  with  respect  to  asset-backed  notes and
     certificates,  including the Offered 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) a copy of the prospectus supplement (the "Prospectus Supplement")
     and the related  prospectus (the "Base  Prospectus" and,  together with the
     Prospectus  Supplement,  the "Prospectus"),  covering the Offered Notes and
     Certificates,  substantially  in the form to be filed  with the  Commission
     pursuant to Rules 424(b)(5) and 424(c) under the Act;

          (iii) a form of 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,  the documents
     described  in  clauses  (iii)  to  (vi)  are  referred  to  herein  as  the
     "Transaction Documents").

     In arriving at the opinion expressed below, we have examined and relied, to
the extent we deem proper, on the Transaction Documents. In our examination,  we
have  assumed  that  the  Transaction  Documents  will be  executed  in the form
submitted  to us, and we have  assumed  the  enforceability  of all  Transaction
Documents.  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
will be consummated strictly in accordance with their terms.

     In  rendering  our  opinion,  we have also  considered  and relied upon the
Internal Revenue Code of 1986, as amended (the "Code"),  administrative rulings,
judicial decisions,  regulations, and such other authorities (including Treasury
regulations) as we have deemed appropriate,  all as in effect on the date hereof
and all which are subject to change or  different  interpretation.  However,  we
will not seek a tax ruling from the  Internal  Revenue  Service (the "IRS") with
respect  to  any  of the  matters  discussed  herein.  Moreover,  the  statutory
provisions, regulations, interpretations and other




Capital Auto Receivables, Inc.

authorities  upon  which our  opinion is based are  subject to change,  and such
changes could apply retroactively.  In addition,  there can be no assurance that
positions  contrary to those stated in our opinion will not be taken by the IRS.
Our  opinion is in no way  binding on the IRS or any court,  and it is  possible
that  the IRS or a  court  could,  when  presented  with  these  facts,  reach a
different  conclusion.  We express  no opinion  herein as to any laws other than
federal law of the United States of America. In rendering such opinions, we have
assumed  that the Trust will be  operated  in  accordance  with the terms of the
Trust  Agreement,  the Trust  Sale and  Servicing  Agreement,  the  Pooling  and
Servicing Agreement and the Indenture.

     Based on and subject to the foregoing, we are of the opinion that under the
existing  tax laws of the United  States of  America,  although  no  transaction
closely  comparable  to those  contemplated  herein has been the  subject of any
Treasury  regulation,  revenue ruling, or judicial  decision,  for United States
federal income tax purposes:

          (i) the statements in the Base Prospectus  under the caption  "Federal
     Income Tax Consequences" and in the Prospectus Supplement under the caption
     "Federal  Income  Tax  Consequences",  to the extent  that they  constitute
     matters of law or legal  conclusions,  have been prepared or reviewed by us
     and are correct in all material respects;

          (ii) the Notes will be characterized as indebtedness; and

          (iii) the Trust  will not be  taxable as an  association  or  publicly
     traded  partnership  taxable as a corporation,  but will be classified as a
     partnership.

     Except for the opinions  expressed  above,  we express no opinion as to any
other tax  consequences  of the  transaction to any party under federal,  state,
local, or foreign laws. In addition, we express no opinion as to the laws of any
jurisdiction  other than the federal laws of the United States of America to the
extent  specifically  referred to herein. This letter is limited to the specific
issues  addressed  herein and the  opinions  rendered  above are  limited in all
respects  to laws and facts  existing on the date  hereof.  By  rendering  these
opinions,  we do not undertake to advise you with respect to any other matter or
of any change in such laws or facts or in the interpretations of such laws which
may occur  after the date  hereof or as to any  future  action  that may  become
necessary to maintain the character of the Notes as indebtedness or the Trust as
a partnership for federal income tax purposes.

     We hereby  consent to the filing of this  opinion  with Form 8-K and to the
reference to our firm in the Base Prospectus under the captions  "Federal Income
Tax Consequences"  and "Legal Opinions" and in the Prospectus  Supplement in the
Summary under the caption "Tax Status" and under the caption "Federal Income Tax
Consequences." 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  Act  or the  rules  and  regulations  of  the  Securities  and  Exchange
Commission thereunder.




                                  Very truly yours,
