That's just a car dealership. They're not necessarily out to screw you, but they are trying to make as much money as they can, so you can't (and you didn't) let yourself get pushed around. The first salesman thought you would buy at $19-20k, and the second one didn't (or he just wanted the sale, or his boss told him to just get rid of the car, or he wanted to scalp the sale from the first guy, etc).
