If you are like the rest of us who have shopped for a used NSX, your ideal car would be the one that was never driven in the rain, always gargaged and covered, washed with distilled water, babied, coddled, never reved over 5000 rpm, etc, etc. These cars are nearly impossible to find, despite what you may read in the classifieds. Your question of whether an owner who modifies his or her car is more likely to drive it hard is a good one, but I don't think there an easy answer. I would suggest that each and every car and owner is unique, and nothing but a very thorough mechanical examination and, more importantly, your own instinct, will help you find the right car. It may be just the opposite of what you think -- is it possible that the guys who modify their cars appreciate and understand the mechanics of the car, and therefore care for them better than the vapid blonde who simply buys the car "because it's soooo pretty"? Bottom line: see each car in person, have it mechaincally inspected, get a title search (carfax), and believe very little else. BTW, after a long search, I bought new.
