 CONT: When the mayor and Dean Wormer are discussing the costs of the  parade, the mayor mentions use of his three Oldsmobiles, but the  white convertible that the mayor and Dean Wormer ride up in is a  Buick, a 1961 LeSabre or Electra. The second red convertible in the  parade is a Cadillac. The first red convertible in the parade might  be a 1961 or 1962 Olds Cutlass, but looks more like a 1962 Buick  Skylark.
