My BF sold a motorbike on ebay to a guy from poland, the guy arranged his own collection too. To start with we arranged to meet him at a service station not far from where we lived, showing him the documentation for the motorbike. He bought with cash with him and as i am wary of overseas buyers, the polish guy came with us to our bank to hand over the cash which was counted/checked by the cashier and straight into our account, no problem. From there we took him to our house where he collected the motorbike. Before he came over we emailed him with instructions on how we wanted to go about exchanging cash/documents (as above) and he was more than happy with, which gave us more confidence that this was a genuine buyer. It was a smooth transaction and if we were to sell to overseas buyer again, we would go along the same route. Try it yourself, don't meet at your house to start with make it a main central meeting point and make sure you accept cash in pounds sterling which is paid directly into your bank - you don't need to explain your reasoning to him, just say this is your terms of conditions & sale, if he questions it or doesn't want to do it your way... pull out of the sale. Good luck.
