play the waiting game, don't act too needy when buying the car. Just remember, they want to sell you the car more than you want to buy it. Ask him for your deposit back and he'll shit his pants and give you the floormats/sunshade for free. Tell him its unacceptable that you will be paying 50k+ for a car and that they charge you for floormats. Let me know where you went, I might be able to find you a better price
