The 94-95's (G50 body) seem to be the compromise of preformance and reliability. I think no one on this (or any other ... less informed) board would disagree, the "stock" 90's have the most, while most 93 and earlier (also G50) are very simliar (discernable by the lack of a grill).
The 96's seem to be the "in-between". They were the first full fledged OBDII, and lowered HP ratings from the 94-95's.
The HP ratings did drop with the 97, but at a lower GVW, the perfmorance diff may not be noticable to all.
I have a 94, and I love it, but if I was in the market today and could find a nice 99 Touring model or 00 Anniversary Edition at that right price WITH dealer verifiable maintenance records, I'd be very tempted to go with the Y33 body.
