He was the original owner, I don't think he had much done in the way of engine work as he told me that the reason he liked the car so much was that all he had to do was put in the gas and get the oil changed. (His favorite expression to me was "You can't break it, it's a Honda") At the same time he is notorius for not paying attention to what he is getting done so there was likely more work done than that. I did notice that after the NSX was totaled (about 2 months ago) he now drives a S2000. From looking at his NSX you would never expect it to have lasted like it did. When I test drove it my wife refused to get in because it smelled so bad from his having old gym clothes and fishing gear in the passenger side seats. The engine ran great and from what I understand from his son (who just married my cousin) just before it got totaled he had just had it completely reconditioned with new seats and new paint. I wish I could tell you more but I don't see the guy much as he is out of the country a great deal now that he has retired.
