On the face of it, this looks like a car that just needs some TLC, ok granted it needs a few thousand throwing at it, but if hes telling the truth, the damage to that rear bumper looks superficial.
I'd love to have a pop at it, sh*te audio system ripped out, stickers off, spoiler removed, wheels refurbed, roof repainted, bumper repaired and painted, belts and fluids changed.
As said above, it wouldnt take much to get it back to a nice standard condition, ok its not going to be showroom condition.
