Yep, that is basically what I wrote "Even if I pay it into a bank (before giving him the car) they may not know until it is too late!". The bank does not necessarily know for sure until later (central clearing etc) if the money is stolen (or v good fake), at which point they will just take the money off me and/or unwind any movement of the money after that? There must be a way to get the bank to check some database of stolen money? I suppose I could ask the bank that. Seller could be a very good con-artist. I suppose I could take a photo of the buyer and take his finger prints on my phone etc, but that does not get me my money back if it all goes pear-shaped! Might put him off though.
Amount is £25K. Too risky me thinks.
