Hi,
I own a RX8 (UK) and can tell you the performance of the car is superb, especially the handling, it goes where you point it and does it very quickly. I compare my car to my others I have had. A Rouse Sport 4x4 RS Cosworth (check it out on the web) a 2WD Cosworth sapphire and Ford RS2000. Tthe RX would destroy them on handling and in the case of the RS2 on performance. The car has it's problems though, mine is in the garage (again) Generally for minor niggles but more importantly (and this may apply to US spec cars also) on a starting issue. The car has a tendency to flood and is difficult to start. But with new concept (type) cars you're going to get teething problems, although I really pissed about it..... Oh and finally, it REALLY turns heads.
I say BUY ONE.................NOW
