Well that's why I'm on about the price, if it's right cheap it doesn't matter if he is otherwise satisfied with the van, doesn't say how old it is or anything, I've had vans with the floor dropping out, and had various engines in but still happy with them as they weren't much above scrap price to start with.I would try and get a full refund, even if you keep it how do you sell on or part ex a vehicle with that history.
