So many options for me.
Aston Martin DB5, James Bond's car. The one used in
Goldfinger,
Thunderball,
GoldenEye,
Tomorrow Never Dies, and
Casino Royale.
Then there's the 1970 Dodge Challenger in the movie Vanishing Point which I'd love to own.
Also a 1973 Mustang Mach 1 used in the original Gone in 60 seconds.
In the end it'll be the 1965
Aston Martin DB5.
