ill throw in my lot , agreeing the 86 was the best of the s3 cars. I had couple of friends that had late (at the time) model stangs. one had a 79, the other an 86 vert... the 79 had such poor quality that the dash plastics were crumbling due to uv deterioration, he had a handwritten sign tapped to it " don't touch dash, it will explode.." of course everyone did, and there were little holes and cracks throughout. At the time the car was only 7 or 8 years old. ... the other friend had a brand new 86, performance package (dont remember which set up it had) and with a set of rims, it was just plain hotness and pretty quick...though i could still run circles around it in my 72 Maverick, he didnt like that much, but his car was much nicer... :)
