I don't think it's a scam but the buyer sent me several lots of forms to sign after he returned to Paris, so I assume he failed to register it and carried on using it for 2 years. I'm not sure how he got away with that? All I did was send a green slip to DVLA to say the car was permanently exported and enclosed a letter with the buyers details. The use of Internet advertising places a shop window to the world, so it's not unusual to get foreign interest on a rare and desirable item for sale.
