They are great cars! I'm pissed with mine right now, but I'm on a few other GP forums and there aren't many complaints with them. Mine has about 140K miles on the body and it’s still in great shape. A few rattles, but most of the luxury features (heated seats, climate control and HUD) still work fine, Do some little mods, maybe a 3.4 pulley, intake, colder plugs, wires, t-stat and no cat and you'll love the car! That should get you about 260-275 whp. But once you start pushing 300 WHP it's going to get expensive with trans upgrades and unreliable. If I could do it over again, I would have stopped with the rockers and just kept it like that. That would have made for a much more enjoyable DD.
Oh and I have never heard of a S/C going bad on these from regular use. People who spray N20 and fuel through them have stripped the coating on the rotors which causes then to heat up, but not stop making boost. Change the SC oil (even though it’s not in the maintenance manual) and maybe while you’re at it the bearings and the coupler for piece of mind.
