tricky this one, but certainly not as described is it? because its a 7 seater, not an 8? other than that, his ebay ad is about as basic as they get, i wouldnt have touched it, no where near enough advert details for my liking, the guys pulled a fast one. Thing is, he says good condition, so thats correct, the car is in good CONDITION, he doesnt mention anything about it being mechanically sound, which I think will be his argument. I would get onto this immediatley, claim its not as described, broke down on the way home, this is not acceptable but as its a private sale, i am not sure where you stand. Certainly report it to Ebay, see if they can do anything, problem there is you are not pay pal protected, and his ad says no returns accepted, grr, a very tricky situation, a very clever ad in its simplicity.
I would also try to find a fix, but dont go spending any money now, lets try and focus on whats wrong, and see if everyone can find a fix?
this is awful, I feel right bad for you Pete, I really do. Let us know your plans, there might be something we can do, even if its just advice....
