The only problem i can see with getting your money back is that it doesn't say in the ad that its built to book spec so that is a bit of a hurdle.As the seller has a 100% rating i would try to negotiate getting your money back and mention you will leave negative feedback and list his ebay id on the forum.Another thought is if poss to take a pic of the chassis on your build table and send him the pic as confirmation as he may genuinely believe he built it correctly.
