BE VERY VERY CAREFUL. Me and my bro where almost conned out of 5k. It was a Nissan Skyline R34 for sale for 5k. Obviously this couldnt be frowned upon, get it, sell it, huge profit. Luckily, the good old british scepticism prevailed and we looked into it A LOT. Basically they get you to pay via western union or another company like this. They say that the company will hold the money till you've received and inspected the product. When you approve, they release the money. These are Escrow companies. I rang western union and my suspicions were correct. They only transfer money direct. The DO NOT hold money. Make sure the seller agrees to let you view it before buying it. If they say that you cant view it, then obviously walk away.
Sorry about the long message, but just want you guys to take a lot of care when it comes to e-bay sales.
Like people say, "If it looks to good to be true, then it is too good to be true"
