Someone mentioned the 70-72 SS Chevelle
I personally like the 1966 Chevelle, It has the Hardtail, it was the original, not changed by consumer opinion.
Eek
When that 66' came out, all the Chevy guys stopped working on their builds, the thing to do if you wanted a hot car, and ran out and bought them. It was the end of an era. But the beginning of another. You could probably find some 64's still sitting in Maine barns 1/2 built. They were the car of choice there at the time for speed, 57's for looks.
