wow, that is pretty shocking like, snotters comes to mind like, ive not seen welding so poor in a long time. its a pitty what happens, the buyer, should have, without doubt, uncovered the wrapping to see the mani, i think if you had done this, you wouldnt have handed over cash for something in that condition. personally, i think its a shit situation, if the seller decides, it was sold as seen, and you had the chance to fit it to your car if you liked, as you picked it up, if he decides that there will be no refund, then i doubt much could be done, if he does offer a part refund, then fair play on his part.
