Congrats on your buy. I too, was debating between a C5 Z06 and a NA1 NSX just because the prices were identical. After test driving both, Ive come to find the z06 is faster in a straight line but the NSX feels so much more quicker and safer around turns. Im sure I could through a comptech SC on the NSX and they would be neck and neck. Also too like you mentioned, the Z06 interior was pure crap. Therefore, I picked up my 92 and have never looked back since. NOW! if it was a C6 Z06, Id be all over that thing in a heart beat vs NA2 NSX.
While I respect the C6 Z06, try my LoveFab turbo on for size and you won't consider a C6 Z06. Now a ZR1 is a different story........
