Let me think back... the ones I miss the most (not in order):
1964 Karman Ghia (first car), light yellow
1972 AMX Javelin, 304, 2-barrel, 3-speed on the floor, split vinyl top, fiberglas hood, dual glaspak exhausts and an 8-track tape player(!), copper metallic I still have fond memories of cleaning and setting the points in that carburator. Ahhh. It was a wonderful thing!

1968 Mustang convertible, red w/black interior
Would have also like to have my dad's red Mach1 Mustang, black Fleetwood Caddy with the big fins and the buttercream Mercedes he had in 1976 or so. The burled wood trim inside and leather seats made it a thing of beauty. It also had the push button start that my current silver Camry Hybrid has.
I rode in a white Bricklin once and that was way cool.
