The only issue or problem I would see is that you'd be buying one of the slowest NSX's :smile:
Honestly though, I don't think there are any year specific problems, or any significant problems at least. You might have some small things go wrong like the window regulators, speaker goes out, etc.... but those things seem to occur randomly. The thing that most people will tell you to look for is the timing belt/water pump service. The rest of the stuff you can find in a search.
