I found a car that i really like but the owner doesnt have the title because he still owes money on his loan. He has to pay off his loan with the purchase $$$. But then im paying him without the title in hand and then he has to have it sent to him and then gives it to me. But whats stopping him from saying the car is stolen after i pay him? Is there a safe way to do this? Would it be safe to do a bill of sale? Is there something else im supposed to do to be safe?
