Bait & switch and fake feeling of emergency are the most common I've seen. "Hurry, if you don't close the sale now on this vehicle it won't be there tomorrow."

Bait & switch and fake feeling of emergency are the most common I've seen. "Hurry, if you don't close the sale now on this vehicle it won't be there tomorrow." ... "Oh, the vehicle you called for? Sorry we just sold the last, we only have the model with X and Y options right now. We could order the one you wanted but it won't be there until next month. Don't worry, I'll make you a deal, it will only cost you [original price * 1.5] and you will have all of those fancy useless options right now! We are friends here, you are lucky I don't offer that deal to just anybody." That and trying to have you believe that paying cash for a used car will hurt you. "Oh, you have $7k in your pockets for that used car we have on the lot? Keep your money! We offer such a low interest rate. Use that money for something you truly care about and leave with the car anyway! No, really... I would feel bad to take this money from you. Here, sign this and the car is yours." ... Loses all semblance of false friendship ... "Oh, you really want to pay cash? Alright. Let me call my supervisor and he will close the deal for you."
