I worked in car sales for a while many years ago. This time of year they do offer huge cuts on last years models. They will show a loss, but that actually doesn't affect them. Dealerships make their money on the factory kickbacks based on volume of sales they do. That's why Thomason was always pimpin volume, it wasn't that he was making less per vehicle but selling more vehicles, he was also getting a bigger kick back from the Factory. Salesmen at the big time dealerships don't make squat on commision, because that bottom line doesn't matter to management.
Best way to do it is to go through the internet sales department of any dealership. Usually you are dealing with their "Fleet" manager who is the guy who takes care of purchasing for the dealership. HE doesn't operate on commision at all and typically is not a "Salesman" Do all you leg work on the phone/fax/email once you have it narrowed down then make an appointment to test drive one. The Internet sales guys are not pushy at all.
