We have all been there and got stung mate. Sometimes it takes a mistake like this to make you think before buying anything on someone elses recomendation or reputation. Take a step back next time and look at everything and use your head not heart when buying cars...TRUST NO-ONE WHO IS SELLING ANYTHING!!!!!!! Make your own mind up instead. Never buy a car in the rain/dark, poor light or from pictures alone. I doubt you've got a leg to stand on askin for it to be repaired or cash back as you've driven it home so you could've done the damage and be trying to chance your luck gettin things done for nothing.( im not saying you are by the way) I would tell you where to go if it was me who had sold it. It's an expensive mistake but i doubt you'll do it again. ;)
