Safest way to accept payment in a car sale

[dhutton]

It looks like I have sold a car and the buyer wants to pay me cash when he picks it up. I don't want to do that since it will raise a flag with the IRS when I deposit it in the bank as far as I know. I am not making money on the sale, I just want to avoid a hassle. I have done this easily in the past when the buyer and I used the same bank but that is not the case this time.

What is the best non-cash way to accept payment and immediately release the car without taking a risk of getting a fake cashier's check etc? I've already been Keislered once this year.....

Thanks,
Don
