We have had an 05 RX8 with the 6-speed for 18 months. The rotary engine is much improved over the old one. My wife loves to drive it and we both like the styling. I enjoy hearing a motor rev about 7,000 rpms. We have had to replace the transmission, starter, and spark plugs. Too high maintenance for me.
It's fun to drive with the 6 speed. Great styling and the suicide doors are a great idea for a sports car.
The transmission is too weak for the power. The trunk is small so the rear seats should fold down. To add an XM radio is $500. Make the stereo upgradeable.
