     We are  generally  familiar  with the  proceedings  required to be taken in
connection with the proposed  authorization,  issuance and sale of the Notes and
Certificates,  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) 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  form of  prospectus  supplement  relating  to the
     Offered  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 June 14, 2001, relating thereto (the
     "Base  Prospectus"  and,  together  with  the  Prospectus  Supplement,  the
     "Prospectus");

          (iii) the Trust  Agreement  and a form of Amended and  Restated  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 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. 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.

          (b) With respect to the Notes and Certificates of any series issued by
     the Trust, when duly executed and authenticated by the Indenture Trustee or
     the Owner Trustee,  as the case may be, in accordance with the terms of the
     Indenture or Trust  Agreement,  and issued and  delivered  against  payment
     thereof,  the Notes and Certificates  will have been duly authorized by all
     necessary  action of the Trust and will  have  been  legally  issued,  with
     respect to the Certificates  will be nonassessable  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 and
Certificates.

     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 Offered  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.
