I don't see why you would sell an RX-8 and buy an S2000. the RX-8 is identical in nearly every respect (handling, power, power curve, etc.), yet its more practical. You're going to get rid of a fun to drive, relatively slow, high revving amazing handling car to get another fun to drive, relatively slow, high revving, amazing handling car, except this time you have two less seats, less trunk, and no roof. maybe someone can point out some more differences between the two but to me they've always been damn near identical.
