Like most things, why get caught up in rigid "rules". Although this site started as a chevrolet COPO and Dealer Site (at least when I started coming here) that was mostly camaro's and chevelles, it has become so much more. I remember when Deuce's became all the rage. Then came the discussions about the Deuce being a "supercar", but only a 350 car. That went on for a while. Finally, my 70 Z28 COPO was discussed. It is a COPO, but the COPO option was a spoiler package. How would that compare to a non "supercar" L78?
I say let's just enjoy em for what they are, and a 427 vette sure is a "super" car if it's not a "supercar".
