Yes, sometimes this happens when a Dealer gets a vehicle with odd colors/trim or other options that don't sell well ( Dealers don't always get to pick what cars they get). Really the only thing I would be worried about is if the tires have flat spots or the Brake rotors have a pulsation from uneven surface rust. make sure the car is test driven at highway speed and to feel for vibration and safely brake a few times from highway speed and feel for pulsation ( The Dealers should have been moving the car monthly to prevent this but it does happen sometimes). There is nothing else to worry about. BTW if it was on the lot for that long and its also the end of the year, he should try and get a really good deal.
