Here's a later one. Officially, I think this is called a "Chevy Cupe SS Serie 2," which basically is saying "Chevy Super Sport Coupe Series 2" - notice it's not called a Nova! I know of 3 or 4 generations of these where the stripe is different on each one. This the second generation stripe. The fourth one is the best-looking, in my opinion, and I think the third one is very similar but I don't recall ever seeing one. There's no car books to learn this stuff with certainty.
