How do I safely buy a car from a private seller?

Meet in a public place, ideally during the day, and bring a friend. Verify the seller's ID matches the name on the title, check the VIN on the car against the title and a history report, and confirm there is no lien, or arrange for lien payoff. Get an independent inspection. Pay with a traceable method like a cashier's check, and get a signed bill of sale. Check your state DMV for transfer requirements.
