^^^ Exactly what i was going to say... You never know who owned the car b4 them or if its a One Owner deal. But I believe if you can afford an NSX, I would believe you would take care of it. Something a quick CarFax report would show. Just make sure the Timing Belt has been changed (if not take care of that), drive the car for 10-15 min in the hot sun,make sure it does not overheat. after get under the car make sure theres no leaks/smoke.
the NSX is still a Acura/HONDA car, itll last you a lifetime with the right care, If there's ppl here with boosted honda's (some with engines over 200k+ miles) and there cars are still runnin like a beast's.. I dont think the NSX would give you any major issues.
