I would also like to see Pontiac brought back. But only if they once again figured out how to "build excitement". Pontiac hadn't done that since the early '70's.
I always had a thing for Oldsmobile cars. So I'd like to see them brought back too, but only if they were unique from the other GM offerings.
Yugo is pretty much an iron curtain Fiat... used to be a guy who autocrossed with us that had one with Abarth emblems on it, he was pretty fast, he was delusional, but pretty fast....
I agree with the Packard crowd. I would also like to see a new Plymouth and the AMC line. Peugeot might be interesting to see over here again. Oh yes and a modern air cooled VW with AC and heat.
