Wreck Cover Up
Another aspect of the Virginia Consumer Protection Act protects used car buyers from purchasing a vehicle when the vehicle’s history has been misrepresented. When a vehicle has been damaged in a wreck, that fact must be disclosed by the seller. A 2003 Virginia case dealt with a dealer who purchased a vehicle from salvage and repaired it, using touch up paint to cover up some of the damage. He tried to sell the vehicle twice, and eventually he had to settle out of court with one of the owners. If a dealer is unwilling to give the full value of the sale back after learning of a car’s previous history, he can be sued for the price of the sale plus damages.
If you have documented proof from the other dealer of them saying it was a wreck, I'd drop that on the GMs desk and say see you in court. Hell start getting on to the owner of the dealer too.
You have recourse, you need to put the footwork in NOW before it is too late, its been a month as it is which means that door is nearly closed on you and you are going to be stuck.
