Would you buy a new 370z that has been in a minor accident?

Zolfix

The dealer around here has a brand new (just 20km) fully loaded 6mt 2010 370z that has been in a minor accident. After 1.5h of negotiating I got them down to 500 under invoice + a full set of nice aftermarket rims (~2.5k)

On the accident:

The dealership's employee crashed the car. He did a 180, hit a curb (major curb rash on original wheels, hence aftermarket wheels), and hit something stationary with his rear bumper. The bumper itself suffered a major dent and apparently a few parts behind the bumper were also damaged. The dealership claims that absolutely everything that even had a scratch on it, has been entirely replaced. Nothing was "repaired" or repainted. No metal has been damaged at all, only plastic parts and only bolt ons, which were all replaced.

I saw a lot of pictures of the car after the accident and it did not look so bad. They even showed me their full repair bill and it was 4.5k. They claim that since it is a new car, if anything at all were to go wrong then it would be fixed under warranty. I intend to pay for extended full 7 year warranty as well.

This accident was not recorded at all and does not show up on carfax.

If I were to go for an accident free new car, it would cost me 2.5k more and no aftermarket rims.

Would you do it? If so, would you pay for a third party inspection? I need to decide in the next 24h...

Thanks!
