As a former S2000 owner (2006) and recently a former MX-5 owner, I have to say they are both great cars. Completely different M.O.'s though. S2000 is a sportscar. MX-5 is a roadster. They are *not* the same thing.
Anyone claiming the stock S2000's I4 was not powerful enough either does not know how to drive one, or they were a passenger in one with someone who also does not know how to drive one.
S2000's gearing was perfect for managing the powerband for spirited driving.
If you want moar power, go buy a balding-man's corvette and enjoy your street-light burn-out's.
If you want an enjoyable sportscar that makes you feel like you are riding a very special rollercoaster everytime you start the thing and put it into gear, grab an unmolested S2000 as fast as you can....
*IF* you can live with the intrument cluster.
I couldn't live with it. I might have kept mine if I could have swapped the instrument panel out for something like that in the MX-5, it would have been near-perfect.
I'm with snowman - the ergonomics were fantastic (short of the afore-mentioned guages), everything so close proximity to the steering wheel and driver's fingertips you didn't even have to take you hands off the wheel most of the time.
I miss mine somedays. But I needed more of a GT-car than a sportscar or roadster. So, for now, it's an FR-S. And no I don't want moar power int he FR-S either. On a track maybe, but that doesn't happen often enough to justify idiocracy.
I won't comment on the Cobalt thread except to say, yeah maybe it was fast as long as you didn't drive it with a pile of keys and nick-knacks on the keychain.
