They changed the price after the deal was made. I took 2 test drives, liked the car, and gave them a written offer. The salesman called and said that his boss, the used car manager, agreed to the price. As I was heading down to give them a check, I got a call and was told that the general manager said they would not take my offer and wanted more money. Spent maybe 3 hours on this only to get shafted. Nice.
