Going back to the original question about paying over sticker:
If the vehicle is ordered by a customer then the vehicle cannot be sold for over sticker, but what the customer/dealership agreed on. However if the original ordering customer back out of the deal, then the dealership can put it on their lot for over sticker. Example: PT Cruiser-every 2001 PT that you see was ordered by a customer. The PT's whose customers backed out, were sold for more than sticker(some over $10,000 mark-up).
