I don't see the prices of '69 Z28's falling. They are hard to find and expensive when you find them, even for a car that had over 19,000 examples made. Supply and demand, they sell. The LS6 Chevelle at over 4,000 made is in demand, I'm not looking for one because I'd rather have another car for that type of money, but I think they are great and attractive cars. Possibly some day I'll break down and own one. I don't think that an LS6 Chevelle with original engine and paperwork will ever be in the $30,000 or $40,000 price in my lifetime.
