Bill of sale. When I'm selling a car I don't ask if the person has a valid drivers license, insurance, etc. so long as I have a bill of sale it doesn't matter who they are or what they do with it. If they are not able to legally drive a car, well, its not my responsibility to check on that. I'm selling something, they bought it, that's as far as it goes.
The difference is that there isn't a federal or state law making it illegal for YOU to sell an automobile to someone who doesn't have a driver's license, or who lives in another state. There ARE federal (and state) laws pertaining to this when selling firearms, particularly handguns. Pertaining to the seller, not to the buyer. (There are other laws for the buyers.)
That said, the federal law does not require a private seller to run a complete background investigation on a prospective buyer. The law says that you shall not sell a firearm to someone whom you know is a prohibited person. (It may say know or have reason to believe, or something like that.) Since the law is non-specific, it's up to each individual to decide for him/herself what level of comfort is required to feel confident that your buyer is not a prohibited person.
You could just ask, and if the answer is "No," leave it at that. For a handgun, a driver's license shows state of residence, but doesn't answer the prohibited person question. A carry license/permit, or an FOID for those states that have such, DOES answer that question.
I don't like the idea of selling firearms, but about a year ago I did sell a rifle ... so I could replace it with a better one. But the buyer was a co-worker, I know he lives in the same state, and I know he already owns firearms because he has joined us at a couple or three Friday after-work range sessions. Therefore, I had no reason to believe he is a prohibited person, I can articulate the reasons WHY I had no reason to believe he was a prohibited person, so I feel comfortable that I have met the legal requirement.
