I love everything about the 03's and below except that you'd have to live with that red interior if you wanted the car in white. For me that's a deal breaker, but for others it's not I guess... I actually like the tan interior.
The 2.2 liter engine, in my opinion, is far more realistic for real world driving and still shines way up high in the rev range. The extra 1000 RPM would be nice on the track though.
I know this thread is old as fvck, but I just thought I'd put my ideas out there. All in all I think the 04 and 05's are the best S2000's to own.
