I am on the north side of Indianapolis, and I almost NEVER see one on the road. It is kind of funny, because usually when I do see one, it will be the one day out of 30 where I am driving something OTHER than my NSX. ARGH!!
I know there are about 8 to 10 in the Indianapolis and surrounding area (including an original owner Zanardi Edition that could use some love...looked pretty ratty when I last saw it), but most are garage queens. When I do see them on the road I still am shocked, my jaw drops, and I openly find myself saying, 'DAMN!! That's an NSX!! Boy does it look good'. Sitting inside of them all the time, you almost forget how cool they look when they go past on the road.
