Most likely it was an '84....however my dad has a '85 and I know what you're talking about when you say its slow. It would seem that going from 135 (celi) to 230 (vette) would be a huge difference. However it isn't. For some reason it doesn't seem to go. Anyway...I listed all the eighties. There was no '83..(well there was but there is only one left driving) and the 82, 81, 80 were all the C3s. Different body style. I just listed the 90, 91 ,92 to complete the C4 generation. Who knows though...she might have not really been trying..or something could have been wrong with the car...and hell you could have just beat it...anyway hope this shines some light on the discussion.
