I am not sure if this is the right place to put this, but I just received a letter from GM asking me if I would allow them to use my vehicle ('03 Avalanche 2500 w/8.1L) for 5-10 days for testing. It basically says that the vehicle will be tested at the Quantum Technologies lab in Lake Forest, California and will be tested through driving simulations and for pollutants.
As a result, I will receive a loaner w/ unlimited miles, a check for $150, and the vehicle will be returned clean with a full tank of gas. Does GM produce letters similiar to this or is it a scam?
