easy to drive and fast enough..
2000 Honda S2000 (AP1)
2001 Toyota MR-S
2001 Mitsubishi FTO
1993 Mazda Eunos Roadster (NA)
1999 Mitsubishi Eclipse GSX
1998 Toyota Supra RZ (JZA80)
2008 Subaru Impreza WRX Sti
2002 Honda Integra Type-R (DC5)
In order of usability...
STI
Supra
FTO
ITR
Eclipse
S2000
MR-S
MX-5.
The last three are relatively a tie...Two seaters with little space for anything but two people. I've only been in an S2000 and MX-5 of those, and I know I'd rather be in the S2000 for longer periods. I can't personally justify an expensive two seater as an only car.
If I were to choose an order though, based on looks/speed/some usability, it would be this:
Supra (gorgeous, power, torque, 2+2)
ITR (basically my car's track-monster of a cousin, beats the S2000 because of the back seat, same track performance anyway, for the most part)
S2000 (great looks, great engine, so much potential)
STI (still good, but getting soft, it gets this rank from performance and usability)
MR-S (razor handling, MR, needs moar motor, no storage)
MX-5 (see MR-S, minus MR, basically a tie here)
Eclipse (despite the potential, I've never been a big fan of DSMs, also - time bomb)
FTO (just no opinion on these...)
