SuperchargedRex - welcome to the board!
Overall, I love the stlying of the late model RX-7's. However, for the reasons stated above, I would not purchase one. The whole "no-piston" thing is just cool. I need to surf over to one of the RX-7 sites to learn about them. Neat stuff, if you ask me.
At our local track we have a beautiful red RX-7 that is there quite often. The owner seems pretty cool. He's put alot of money in the stereo, HUGE exhaust tip, awesome wheels, boost gauges, etc, etc. Anyways, I have seen him race on many occasions and I have not seen him crack into the 13's once. Each time I see him at the track I think that he has got to get into the 13's this time...but still can't. Not sure why. But his car is always very clean, has a nice stereo and some wheels that probably cost as much as my future ProCharger!
Take it easy,
