who is into "later" cars

I think they're cool, and I wanted one very badly in 1979. Kinda still do.
They can still be found inexpensively since there on the undesirable list still. An excellent example to show and go will cost under 10K. There out there. Mostly in the middle of the country like Ohio and many can be found in Washington or Oregon.

How bout the Aspen/Volare, I think those cars can be made into something. They had a Road Runner version and wasn't the Aspen offered in an R/T?

Yes, both are correct. The Plymouth had the Road Runner version and the Dodge had the R/T Super Coupe. There biggest draw back (up doin so to speak) is there weight. Also the ISO suspension.
Go to the FMJ only board.
