 Board
        of
        Directors of Nissan Motor Acceptance Corporation, as Servicer
 Torrance,
        California
 
 
 We
        have
        examined management’s assertion that Nissan Motor Acceptance Corporation (the
“Company”) has complied as of March 31, 2005 and for the period from June 24,
        2004 (commencement of operations) to March 31, 2005 with its established
        minimum
        servicing standards described in the accompanying Management’s Assertion, dated
        June 20, 2005, for the Nissan Auto Receivables 2004-B Owner Trust. Management
        is
        responsible for the Company’s compliance with those minimum servicing standards.
        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, as adopted by
        the
        Public Company Accounting Oversight Board and accordingly, included examining,
        on a test basis, evidence about the Company’s compliance with its minimum
        servicing standards 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 its minimum servicing
        standards.
 
 In
        our
        opinion, management’s assertion that the Company complied with the
        aforementioned minimum servicing standards as of March 31, 2005 and for the
        period from June 24, 2004 (commencement of operations) to March 31, 2005
        for the
        Nissan Auto Receivables 2004-B Owner Trust, is fairly stated, in all material
        respects based on the criteria set forth in Appendix I.

 As
        of
        March 31, 2005 and for the period from June 24, 2004 (commencement of
        operations) to March 31, 2005, Nissan Motor Acceptance Corporation (the
“Company”) has complied, in all material respects, with the Company’s
        established minimum servicing standards for automobile loans serviced by
        the
        Company for the Nissan Auto Receivables 2004-B Owner Trust as set forth in
        Appendix I (the “Standards”). The Standards are based on the Mortgage Banker’s
        Association of America’s Uniform Single Attestation Program for Mortgage
        Bankers, modified to address the unique characteristics of servicing automobile
        loans.
