Well i think it just shows what sort of trader he is? Every trader would normally properly go over any car before they pay for it as at the end of the day they are trying to sell the car on to make profit and so they wouldnt accept anything that they have to spend money on to sell on. He doesnt have a leg to stand on and even if he has your address there is nothing that he can do. This is the whole point of ebay, SOLD AS SEEN.
