<prompt> Human: I told a potential buyer that I would be able to work out a deal with him. Im selling the car for 5k, and hes willing to put a large down payment of 3.5k down. I said maybe we can set up an installment plan for him to pay the rest. As a private seller, what can I do to make a legit contract that holds up to the law if something goes wrong? Is there a such thing or is this an honor code situation?  <response>: You can tell him to find someone else to loan him the money. Absolutely under no circumstances EVER. EVER. EVER! should you go along with this. Are you a bank? A car dealer? Do you have contracts with collection agencies and repo companies? No? THEN DONT DO IT!
