What one car did you sell that you wish you had back?

I could probably put any of the three '69 Road Runners I've had at the top of this list as I just love those cars, but I think the one that I should have kept was a F8 1970 Challenger 340 4 speed. It had a custom paint job typical of the psychedelic seventies and had a few bolt-on goodies, but that car drove like a dream. I sold it when I joined the USAF in the early eighties and needed to thin the herd so as to not leave too many cars behind for my father to deal with. In retrospect I wish I would have put it into storage somewhere...
