While the Cuda/Challenger concepts are awesome looking, I wouldn't want Detroit to produce an updated version.
Guess I'm a purest, but I want something to drive that doesn't look like a car that every Tom, Dick and Harry is driving. Case in point with the Mustangs.....Didn't you used to turn your head when you saw an old classic Mustang fastback on the street? But now days, it seems like there's a what looks like a classic Stang on every corner. The new ones take away from the wow factor of the originals, and I frankly don't want that for my 'Cuda.
Anyway, just my 2 cents.
