I, Donald H. Wilson, the President of M&I Dealer Auto Securitization,

        of M&I Auto Loan Trust 2003-1

2.	Based on my knowledge, the information in these reports, taken as
        a whole, does not contain any untrue statement of a material fact or
        omit to state a material fact necessary to make the statements made,
        in light of the circumstances under which such statements were made,
        not misleading as of the last day of the period covered by this annual
        report;

3.	Based on my knowledge, the servicing information required to be
        provided to the Indenture Trustee by the Servicer under the Sale and
        Servicing Agreement for inclusion in these reports is included in
        these reports;
