Its pretty simple when selling a car private, payment in cash, never accept personal cheques (a few people still use them these days), even a bank cheque(they can be cancelled).Test drives, ask to see drivers licence, always go with them, get the key back before you get out of the car.CHANGE THE OWNERSHIP OVER BEFORE THEY TAKE THE CAR, A piece of paper signed by both parties with time and date is worthless. no if's or but's, do it on the internet, if it cant be done at post shop etc, the buyer will just have to come back when it is done.A buyer has no comeback if something goes wrong, "caveat emptor" applies (buyer beware), its up to them check the car and make a decision.
