If the repair were done correctly, I could still be interested in a clean car with a prior accident - if the repair were subpar, I would likely not be interested, unless the car had a specific purpose, and the repair were non-structural in nature.
The car you're referring to looks amazing in person, one of the 10 top cars in terms of appearance, but from what I hear, there is structural repair which was subpar - if you're really interested in this vehicle, the next step would be to take it to a quality frame guy to have the car measured on a rack, and ensure the car is square. The main concern I would have, is if the repair appears to be subpar, what is the quality of the welds and structural work that you cannot see? Unless these serious repairs are documented, it becomes something of a 'assume the worst' situation.
Its unforutnate, because the car appears to be clean, and was tastefully modified. You will need to decide on your own if you want to continue spending time, and money, down this road, but, as I mentioned above, the next step would be to take it to a frame guy. This is a few hundred (around $350), if you wanted a quickie feel for the car, just get an alignment performed - if the car cannot be aligned, you know its tweaked. If it aligns fine, perhaps you can continue your interest - the other recommendation I would have, is to get the thing on a rack, so you can see the severity of the accident, and get a feel for how it was repaired.
thats the good thing about this, title is clear, and these threads will be deleted by the time I sell the NSX
This quote concerns me somewhat... you feel lucky to have come across this information prior to making a decision on this car, yet you also seem to imply the upside of this car is that by the time you sell it, a future buyer would not have the same information at his disposal - this seems somewhat underhanded, if you buy the car, make an informed decision, know what you're buying, and why, and give a future buyer the same basis for his decision.
