Being a new S owner myself I say go with the S man. This thing is soooooooooo much damn fun to drive! I'll admit, before I got the car, I was like man i'd never put that top down....now you never see me with the top up! Lol

Of course, my opinion is super bias, and i've never ever been inside an RX-8. Take'em both out for a spin before you make a decision of one over the other. Yes there are a lot of S2K's on the road, but I put money on it that there's only a handful that are done correctly around here
