1) Replacement tires - I just replaced my rear OEM Bridgestones at 6,500 miles...obviously the OEM Bridgestones and Yokos don't give you many miles. Responding to my queries about alternates, NSXers who desire longer life tend to favor the Dunlop SP9000s...there is a trade off in performance, but you get many more miles. Check the FAQ for more info on tire options.
2) If you're going for the Targa, I strongly recommend the 97+ cars. I wouldn't even consider the earlier models. Keep in mind that the Targas are heavier and roll more than the coupes, so the 97+ 290HP engine and 6speed tranny help offset that considerably. Additionally, the 97+ NSX-Ts have additional rigidity to compensate for losses due to the Targa mod.
3) For Targas, 1997 is your best bet. For coupes, I'd go with a 1994 model.
