I have an AP2 S2000 with ~9500 miles (2004). The car is so quick to respond and has great handling balance on the track. The only complaints are that the seats aren't that comfortable and there is no elbow room for me (I'm 6'2, 170lbs).
It's loud with the softtop but livable with a hardtop. Wish I had Aux input or iPod for the commute, but I guess it's more of a toy car than my E90 M3 so I can live with it.
I was actually thinking about trading it in for a Cayman S this week. This thread is making me reconsider.
