Huge bummer on the J.. Been a while since we've had a member wreck their car....
Optimally you need to search the forums, but I'll give you a run down on everything
G50-90-93: Said to be the best performing. Ive driven <a perfect> one and they definitely are faster. Mainly from a higher 1st and 2nd gear, but they do start in 2nd. Problems are the timing guides and some other minor things, mainly caused by lack of maintenance94-96: Timing guides no longer an issue, and they gained MANY new luxury features. They got a grille in the front too. Much plusher, quieter, but have a lower 1st and 2nd, and makes them slighly slower. I personally like the 94-96 better, as there are SOO many things they changed to make it more reliable. 94/95 models are the ones you want, as 96 has OBDII. Many things like heated seats, traction control and stuff like that.
Overall, the T model is probably the one you want, and if you dont mind dropping cash for the ultimate vehicle, go Q45a. hard to find, but once you rehab the active suspension you will own one of the top 5 most complicated cars ever created. NO DIVE, LEAN, or SQUAT up to .5g.
Y33Total redesign, engine powered down (VH41) to 260/278 (VH45 was 278/296), and definitely not as sporty. More lexus-y, and IMO is a downgrade....
I think the one you should look for is a 94 or 95. If your close to indy, there are 2-3 really nice looking Qs id go look at for/with you.
