I saw the same thing in Northern VA. That dealer wanted about $4400 over list, but was willing to honor the incentives. My experience is that these cars are available for a bit under list, plus Pontiac discounts. The market is tight for new cars and most dealers will deal. If yours will not, contact another local Pontiac dealer and they will "find" the car that is marked-up and work a trade.
Good Luck!
