Someone mentioned a different color front bumper repaint combined with a story of being pulled over doing 140. Makes me scared when I fear that the original owner was a I'll shift at 7500 rpm all day because I can type of person. Being a CTSC car makes me worry about additional wear (not scientifically proven just more of a fear) over a non CTSC car.
I spent $1000+ in gas, turnpike tolls, southwest flights, hotel rooms, and PPI's to check out & find the right car. Also one of the most memorable things I'll never forget before picking up the one I bought was this excerpt from an email by the seller:
"Sounds good with the tires. Same brand and all. Make sure they balance them correctly and while you are at it have them spin balance the fronts. I got a slight vibration at 130 that I did not have with the original tires.

These cars are meant to be driven.
If I were in the market still (and I would definitely have checked this one out already if I didn't buy one in May last year), I'd not worry about what little anecdotes have been told about the car and would contact the seller, learn what you can from him, see if he'll give you the contact info for who serviced it most often or most recently, talk with them, and then if all sounds good then fly out and look at it in person or ask an NSXPrimer or NSXCA'er to stop by for a look (or email socalx above), followed by setting up a very thorough mechanical PPI with a nearby known NSeXpert if you're so lucky as well as a 2nd PPI by a reputable body guy, but that's just me!! Sometimes you only get one chance every 10 years or ever to find a "right one," be it animal or mineral (hopefully not vegetable).
This one may be perfect for someone or may have inherent problems for a certain buyer, but there's only one way to find out.
Even better yet - I'm willing to bet there's at least someone (or more) right now who has not posted in this thread and who's doing or done all the above. Has to be.
