I drove a C4 (LT-1, but an auto) today and it doesn't even compare to my '03 Z06. The C4 was in ok shape, 195k miles, tranny leaking oil, brakes sucked, but in better than average shape considering the mileage - it would probably make for a good track car, but I'm kinda like the small size of the S2000. Having the Z06, I don't know if I'd ever be happy with the C4.
