Matt, you can build MOST of these, some easier than others:
1933 Cadillac Fleetwood Aerodynamic Coupe---NOPE
1955 de Soto Flightsweep----NOT that I can find?
1956 Continental MkII Coupe---there was a plastic toy, not very accurate. There is a 1/24 diecast I think?
1959 Buick Invicta Coupe---AMT annual
1963 Corvette (Corvair? The caption is a bit unclear) Fastback Coupe---YES, CORVETTE...just reissued AMT, or nicer bodied Revell snap kit
1966 Oldsmobile Toronado---Johan
1970 Dodge Challenger---AMT
1971 Ford Mustang Mach 1---AMT, MPC
