I've agreed a price on the car and will likely get a shipper to do the transport. The scary thing is I will have to transfer the equivalent of $14,000 to the seller on trust that the car will be there for the shippers. I have no security whatsoever this way.
Airfare prices have been low of late.
I would not send a penny without confirming the car first.
Visit and pay in person, or use an escrow service.
At the VERY least get a "Proof of life" picture.
This can be as simple as a new picture of the car with the seller standing next to it making an OK sign as you have requested. A pic with a copy of that days Times lying on the bonnet would be good too.
You said "Europe" but not which country, have you seen any ownership documents?
