Wow, that's an awful story. But first things first:
Why would you EVER buy a car from another state without getting a carfax report on it? It cost like $10
There are so many things he could have done better here. Among others, there's no excuse for him not test-driving an identical car locally, even if it was twice as expensive. How would he have known what to look for? Second, that title thing is total BS, you'd be stupid not to get a bill of sale if you hand someone cash for a car. Third.. well I'm not even going to get into it, but it sounds to me like the buyer did almost EVERYTHING wrong. What's amazing is that according to the story, he did everything wrong over a period of like 3 days?!? Somewhere in there he could have had the car taken to a shop, he could have done some more inspection of his own, etc.
