The Z is faster, but the S2000 is sportier. And as much as I love the Z, I'd go with the S2000 if those were the only two choices. Too bad the S2000 is no longer made. BUT, if you ask about the 370Z versus the S2000, then I'd go with the Z. The new Z is not only sexier, but it also has one of the greatest manual transmissions in the entire world.
