Bought from a friend of a friend
Tomás in Torrance got what looked like a deal. A friend of a friend was leaving town, the price was right, and the title changed hands in a parking lot with a signature already on it — a name Tomás did not recognize, from an owner two sales back. The car ran, so he drove it. Now he wants to sell it, and every buyer asks the same question he never did: if your name is not on this title, whose car is it, exactly?
The honest answer is that the paperwork and the driveway disagree. In California, the person on the title is the owner the DMV recognizes, and a chain of hand-to-hand sales that never passed through the DMV leaves gaps no buyer should accept. Tomás is not stuck, but he does have to repair the chain before a clean sale is possible — and the one thing he cannot do is simply pass the stranger-signed title along to the next person.
