Assuming OEM stock Hondas.
1. '00 or '01 ITR
2. TSX (Type S, when available)
The NSX has never hit on all cylinders for me...something just seems to be missing in the execution of the concept. The new iteration about to hit USDM could change my mind.
The S2000 I don't fit in very well for some reason (6'3", 220#), and I hit the track too much for a convertible that's so hard to fit with both a cage and my helmeted bus head.
The TL is a great car, but just a little bigger than what I normally like to drive.
