I know very little about Ebay but a relative (slightly vulnerable and elderly and especially naive) has bought an item for a lot of money on ebay - a car. He sent a deposit by cheque and then paid cash on delivery but is now really disappointed with it as it is not very good at all and in much poorer condition than expected. Is there any way of getting some money back or returning the item if the seller doesnt want to or is it a case of he bought it, paid for it and buyer beware. Any advice really appreciated even if its just tough luck!.
