Well if you are going to compare the two, you have to understand that one is a roadster, the other is a coupe. Of course the convertible roadster isn't going to have as much room, or cargo space. On the same hand, the coupe doesn't have a convertible top.
350Z and S2000 straightline is a driver's race, bottom line. It is probably easier to get 13's with the 350z, but it is a driver's race, none the less.
Roadcourse, sorry, the S2k still owns the 350z.
No, there is no such thing as the S2200 coupe. That has been debunked a long time ago. there is a magazine that likes to publish tabloid stories and the like and make it look real. However, you can clearly see the photos in the mag were photo-shopped. Even so, Honda has always been so tight lipped about everything it comes out with. You won't see pictures or specs until right before the car comes out. Just like with the new accord. Honda has said, there is no other car coming out that is in relation to the S2000.
