Chrysler or Chrysler dealers? I'm curious since it is very much common practice for dealers to fix stuff that happens on the lot and never disclose it to buyers. They employ people who come to the lot at regular intervals to just take dings and stuff out of cars.
To the OP, remember that when it comes time to sell the car, savvy buyers can tell with the use of a paint meter whether or not a panel has been repainted. If they do this, they can make the incorrect assumption that your vehicle was in an accident.
This is one beef that I have with insurance payments after accidents. If the car is worth $10k and has $3k worth of damage, they pay you $3k to fix the car. Unfortunately, this only brings the value up to whatever amount someone will pay for a damaged / repaired vehicle, which is almost always lower than the $10k in this example. It seems to me that you should be compensated to bring you full whole, which should include an amount for the depreciation that was also caused on the vehicle. But I'm completely digress...
The point is it's great that they fixed it, but it's still annoying, IMO. As for the hood damage, I think that one, as mentioned by others, is going to be hard to prove. Is it something that could have been caused by something while you were driving?
