Few scams running on there.

One is, get you down with cash and batter you and take the cash.

The other is usually a scam to extract your bank details or do you on a shipping costs scam, mate email three and got the same email back, guy moves abroad, take the car, now selling the car and will send it back over. They send a bankers draft for shipping(fake) and you pay the shipping your end (claim that is how it has to be done for one reason or another) then they will bring the car over to you, and you pay for the car then, once you pay the shipping it's end of deal, they own the bank account in the shipping companies name (made up company).

Thus keep your shipping payment iirc
