Went to school out on Long Island, early 70's. I remember seeing a lot of 4 door Chevy Impalas, Ford Galaxies, big Buicks and Oldsmobile. Only Mopars I remember seeing were Valiants, Furys. Basically, if you could afford a car, you were driving in an old 4dr family sedan. Only cool car was a guy owned a'63 2dr Impala. Don't know what he had under the hood, but he could do a burnout with little effort.
