The mid70s-80s didn't have many "sporty cars" at all. A few had some horsepower (GNX) but were built on old platforms with things like solid rear axles. I was driving a slow minivan with a 5 speed gearbox.
My last semi-sporty car was a 1973 Nova with a 350 that would do 0-60 in 8.5 seconds. My little CUV is quite a bit faster (7.1 by the mags).
