Foreign Scammers
If this guy says that he has a shipper/importer and says he sent you a check certified or other type check etc, for example $2000 more then your asking for your car and then asks you to then wire his importer that $2000 money from that check for shipping. Then its a scam. Dont send him or anyone else money. its the oldest scam in the book.
Once you get his check, immediately cash it. If you get green money in your hand ..then (Obviously) its OK and you can release the vehicle.
