How much are looking too spend? Do you want a project or something already done? I would start by picking up a classic car trader. You can get them anywhere you pick up an AutoTrader. Or http://www.pjsautoworld.com/1940.htm there on Gulf to Bay. I pass by every day, but you'll pay top dollar. I was in there a few yrs back and the guy I spoke w/ was very nice. I was just browsing through one day.

edit - alot of times the best way to find these cars is sitting somewhere and just inquire or word of mouth.

We've got a friend w/ a Cuda thats been sitting for a while in his shop, I think it's purple, I can't even remember now . Great shape, but needs a motor. We've been trying to get him to get it back on the road for the longest time now, hopefully someday.
