You are wrong. 1968 had cars made by every manufacturer that looked good. Every car was performance oriented. Chevelles, Cutlass', Skylarks, GTOs, Cudas, Darts (w/426 Hemi), Mustangs, every car out that year looked good.
Now lets go into the future. GTO, yes and ....? Where are all the good looking power driven cars. Oh yeah, the mustang is from 68. The charger, well its appearance speaks for itself, boo boo. Camaro, Firebird, cuda, challenger these great cars are long gone. There are no modern day muscle cars except for the GTO. Mustangs are pony cars, always have always will, and the same with camaros and firebirds.
