The RX-7 was only in the USDM for 4 years, '93 to '96 I think. So there aren't too many of them around and so the asking price would usually be higher. They are a lot of fun to drive and is a "truer" sports car than the Z32, which is more of a GT. But their reliability is pretty dismal even compare to the tt. The rotary engine only lasts between 80-100k in general. There is also some electrical issue IIRC. Road & Track or Sports Compact Car just had an article on buying an used FD couple of months ago.
