I've driven both ap1 and ap2; obviously the more torque in the 2.2 ap2 model gives it a quicker acceleration but still, the ap1 is not that far behind and revs obviously a thousand rpms higher. Looks wise, I love both models but I think the ap2's factory wheels and lip kit etc looks even more aggressive than the earlier models. But an s2k is an s2k and I'd be glad with any model but if I had to finance something that new anyway, I'd go with 04+ (ap2) imo.
