In the Cadillac showroom, the salesman refers to the blue car as a Coupe de Ville, which it is not. A Coupe de Ville would have "Coupe de Ville" scripts on the rear quarter panels. This if further confirmed in the park scene showing the instrument panel and the open door. The door panel proves it to be a "Sixty-Two" model (not to be confused with the year). Cadillac Sixty-Twos were the least expensive Cadillacs offered.
