<prompt> Human: My brother in law is trying to sell a car for 1700. The person offered him a check and said once it cleared he would come pick up the car. Is that okay? Or is there anything I should warn him about? I dont want him to get scammed in any way. He is eager to get rid of the car.Assistant: Most likely a scam. Has the guy agreed on paying the 1700?Human: Yeah he said he wouldnt pick up the car until the check cleared. But he was adamant about buying the car and called him like five times in a row when he didnt answer today which made me uncomfortable.  <response>: There is no reason not to get cash in your hand. Why would anyone agree to a check and wait for weeks for the check to clear. It makes no sense. And yes that is how long it can take. The bank can come back later and say it didnt clear. If someone wants the car why wouldnt they go to the bank, get the money and finish the deal right then and there.Banks say 30 days before the check clears with no chance of a problem.
