<prompt> Human: I recently put an add on Cars.com for my vehicle. Someone responded a few days after, and we agreed on a price. He said that he was out of town but that he would be in touch after he returned to the area. In my mind the deal seemed settled. That was about a week-and-a-half ago.Yesterday I got a message from someone asking if the vehicle is still available for purchase. I havent responded yet.Now, technically the vehicle is available to whoever I want to sell it to on the private market. After all, no one signed a binding contract or anything like that. But am I obligated in any way to wait for the first guy to respond? Is there an appropriate length of time to wait before getting the other person on the line? If I say yes to the second person and get a better offer, can I just go with that one? What would a reasonable, well-adjusted individual do here? Thanks  <response>: No youre not obligated. He didnt give you an exact time of when he would be available. If you have not heard from him in almost two weeks, I would start selling to someone else. It would be different if say person 1 was working on getting financing and needed a few days to get it done. Hes simply away and you have no idea when he will be available. Move on to a different buyer.
