This is why I always do out the door pricing. They can arrange the numbers anyway they want on their sheet, if it isn't the price I agreed to when I go to sign the paperwork, they are either changing it or I'm walking out the door. Until you sign the paperwork you can walk anytime you like. Lots of people don't seem to understand that and they end up agreeing to things they shouldn't. But I also make sure to have my own financing ready to go before I buy the vehicle if I'm not paying cash, which seems to be another things a lot of people don't do either.
