I second the Corvair--I'd also like to see some of the muscle cars of the 60s and 70s I'd like to see the '69 Pontiac LeMans and '70 GTO, '71 Chevy Malibu, '72 Oldsmobile 98 and 442, '79 (Blackbird) TransAm. Preferably in convertable versions. I'd also be interested in GM body shapes used by more than one manufacturer. Ones that could be modified by custom props to change the make and model.
