I don't know about cars, but I had this happen with a boat that I sold in Florida. The buyer is supposed to register the boat. The registration sticker did not expire for another year. So, they didn't bother to pay the fees. When I went to the DMV a few months later to renew a car registration, they thought that I still owned the boat. They said it happens all the time. I had the bill of sale to sort things out.
