I *almost* fell for this one, buying a Jag on eBay that was based in Hungary. The seller kept exhorting the security etc. of escrow and supposedly contacted Fortis (a £30b yr turnover genuine merchant bank) who then supposedly emailed me with bank account details.
I got suspicious, rang Fortis independently, and was told that although they DO have an escrow service, it is NEVER USED FOR CAR TRANSACTIONS. It's only used for Big Bucks - oil, manufacturing etc.
