If you rate a new car a 10, then what of those that has been test driven hard?
We all know that most people who advertise a car that is a 10, wants the car to be checked out. They might be even claiming it’s a 10 for this very purpose. It works too or else we would not be having this discussion.
Most NSXs out there will be in a used condition, so a "10" claim in my opinion would be relative to other used NSXs out there. Bottom line, this is very subjective.
I can claim that my car has never seen rain because I ordered mine new from Acura, and literally watch the car being unloaded and transported to the dealer. I was there when the PPI occurred, and took official delivery of it immediately (Jon Martin made this all possible).
The car was clear bra'ed immediately and rarely driven (less than 900 miles to date). I still service the car at the exact time intervals, and all the factory tags on the shift knob and the one hanging out of the glove box are still there, just like a new car.
I don’t know how you can claim a car has never seen rain if you are not the 1st owner, and did not go through what I went though. Even a new car sitting at a dealership outdoors has the possibility of seeing rain.
I never liked using a 10 point scale, so if one day I were to sell my car, I would just take the time to explain in detail the condition it is in. I might even make a claim that it is as close to a brand new car as you can get.
