This happened to me, I had a VW GTI I watched them back it off the transport truck with the protection on it. Come time to trade it in, they came out with the scanner, and they had repainted the whole front right, and right door at the factory. Sold it as new.Happened to my friend and is WRX. Dealer told him his car was delivered and then the next day called and said it wouldn't be ready for another 2 weeks. He's a technician and had the tool, so he measured the paint and found the whole door was repainted.
