INDEPENDENT ACCOUNTANTS' REPORT

Board of Directors of Nissan Motor Acceptance Corporation
Torrance, California

We have examined management's assertion that Nissan Motor Acceptance Corporation
(the "Company") has complied as of March 31, 2004 and for the period from June
17, 2003 (commencement of operations) to March 31, 2004 with its established
minimum servicing standards (herein, the "Servicing Policy") identified and
included in the accompanying Management's Assertion, dated June 18, 2004, for
the Nissan Auto Receivables 2003-B Owner Trust. Management is responsible for
the Company's compliance with the Servicing Policy. Our responsibility is to
express an opinion on management's assertion about the Company's compliance
based on our examination.

Our examination was conducted in accordance with attestation standards
established by the American Institute of Certified Public Accountants and,
accordingly, included examining, on a test basis, evidence about the Company's
compliance with the Servicing Policy and performing such other procedures as we
considered necessary in the circumstances. We believe that our examination
provides a reasonable basis for our opinion. Our examination does not provide a
legal determination on the Company's compliance with the Servicing Policy.

In our opinion, management's assertion that the Company complied with the
aforementioned Servicing Policy as of March 31, 2004 and for the period from
June 17, 2003 (commencement of operations) to March 31, 2004 for the Nissan Auto
Receivables 2003-B Owner Trust is fairly stated, in all material respects based
on the criteria set forth in Appendix I.
