I've always wanted the following, due to either they're cool, have character, have history....
Mk1 Golf
Chevrolet Camaro Iroc Z (80s)
Chevrolet Blazer (80s)
Chevrolet Monte Carlo (80s)
Vaxhaull Chevette
Old Ford Escort (normal one)
Ford Escort RST
Some form of TVR
Morris Minor
Classic Mini
Old school VW Beetle
Old school VW camper
I'll probably add more later.
