I'm more concerned about the intentional rollback of the odometer, and the "craigslist stoner". Usually they buy auction cars and try to sell it to the unsuspecting high school teenager looking for their first car on their own, who has their parents "cash". Usually it winds up in a seller that can disappear after the transaction never to be found again, a teenager that is grounded for the rest of their high school tenure, and a parent that puts $2k of repairs into the car Before realizing it needs another $3k of work ...and sells it for a loss in a few months.
You can take it for an inspection before buying, but I figure an inspection won't find a lot of the stuff wrong with the car.
Sorry, I'm cynical. it's your money, your decision. It's just a car. It's not like you're deciding between brain surgery or not.
