If the car you decide to buy has a loan on it, then that loan has to be paid off and a letter to that effect issued by the bank. And the paperwork needed by the police station will also have to be signed by the loaning institution.

Point is, it make take another trip to get everything done. When you are looking at cars make a point to ask if there is an outstanding loan.

An observation of mine is that the best prices on used cars are directly from individuals. I have bought two used cars here. The car dealers have to mark up to make their money. Also, it is good to know who owned the car and how it was driven. You would rather have a car that was cared for and not abused.

Good luck.
