Interesting...
I just bought my first NSX (1991 Black/Ivory) and presently own a 07 Honda S2000 as well. Two thoughts have crossed my mind lately:
1. Keep both the NSX (of course) and S2000 as both give two very different and equally cool driving types. I've got the convertible, high rpms, and chuckablility that the S2000 provides and have the coupe NSX, handling, and exclusivity that it provides.
2. I was thinking of also purchasing a newer NA2 version of the NSX but after driving my S2000 this past week I forgot how killer it is as a daily driver! Love this car as well.
So in conclusion I think I'll start modding my NSX (exhaust, new wheels, maybe comptech supercharger) later on and keep the S2000 as my daily driver. I do love the look and refinement of the newer NA2 NSX but I can't afford and have all 3.
Seriously test drive an S2000 if your looking for that open air feeling and especially as the car is a riot to drive.
