I owned one. Bought it new, bright yellow, 3 speed on the column, and a 307 2bl with a wopping 200 hp. Or so it claimed on the airbreather. Power nothing, all the engine had was an alto, One fan belt. $1700. out the door. I litterly beat the living crap out of that car. Overhauled the engine twice, a couple of dozen clutches, and several rear shock mounts. I added a 4bl and headers, It would melt a set of L60's into the pavement, but it was dead after first gear. I have no idea how rare they are, the chevy dealer I bought this from sold a bunch of them. It was cheap even for that time.
