Put yourself in theirs shoes. You have a car for sale on ebay and have a couple of hundred watchers, with several UK buyers interested in paying cash, in person, and collecting the car. You then get a couple of people from nigeria who want to pay be western union or some other money transfer and arange for someone you dont know to collect the car.
Would you sooner have a local guy pay you cash or take a chance and sell to someone in another country?
The green one was a bargain Pete and they don't come along very often. Mike wanted $7800 for the car and that's what I bid for it. I'm just waiting for the registration docs to come back so I can get out and enjoy it.
