Uuuuuhhhhh I may be having a senior moment but if my memory file I just pulled is still good, The first IROC;s were released in '84, I worked at the dealer and we recieved a few they were hard to get and people lined up to get them, I think we only got in three?? My buddy bought the Black one, the loan officer drove the yellow one as a demo for awhile and I dont recall what the third one was, It left the lot as fast as it rolled off the truck, the Black one had so many things wrong with it you would not believe it, it was in the shop almost every week, he finally gave up and GM took it back under the lemon law at about a year, I dont recall where the car went after we got it back, they were not all that fast, but we did lust for the wheels and tires off them
Bud.
