It would have to be the Gran Torino from Starsky and Hutch with its red paint job with iconic white vector. When I was a boy, I used to practice sliding across the bonnet of our car like Paul Michael Glaser does in the opening credits. My father caught me one day and gave me a thick ear.
Dodge Charger for the dukes of hazard. DeLorean DMC-12 which they are remaking as an electric car in America. TVR-Tuscan S in Swordfish has to be my winner though.
There's a Peugeot 207 that you see for about 1 second in A Quantum Of Solace. It's in the bit with the bad guy chasing Bond. A lovely metallic blue with nice alloys.
The James Bond white Lotus that doubles as a submarine, would love to own one. And live next to a beach.
