The two most recent ones I have seen are the “We need a deposit before we can even give you a price” and if you don’t have the car they want, tell them you will get it, call them up in a week and tell them they have it, then when they show up give them the keys to their new car which of course is one you had on the lot last time and is very little like what they really wanted, but maybe they will not notice before they drive off the lot. Then of course they always treat women as idiots and if a man is with him, always talk to the man as if he is some sort of interpreter.
