This Red ’57 Corvette actually belonged to my sister (and I imagine some day I’ll have to make an effort to get it back to her.) I remember the opening doors making it a popular choice at playtime. 

This example is red with white side tampos, blue tinted windows, and standard wheels.  It features a bare metal base and chrome plastic bumpers, though in this instance most of the bumpers have broken away.

There are several wheel and window variations of this casting as well a similar casting (#1039) with fixed doors.
