Don't think I'm going to progress this one. Few things are raising red flags for me, not least that latest MOT has an advisory: "Rear Sub-frame corroded but not seriously weakened"!!
He sent me some better pics of the bumper damage (see below) - to me it looks more as if the car has been hit from the side rear (rather than a simple a bump to the rear) which has then pushed the whole bumper out of alignment. I dread to think of the make-good cost for that! He said he bought the car as Cat N and that the previous owner had replaced the bumper (which I doubt), so do wonder if he is just trying to 'flip' it.
His email (from a PL domain) said "I went around and took pictures of the damages....... I don't have an engineer report as I bought it with category applied on and previous owner advised that he replaces the rear bumper. The front wing has a damage from catching the curb at the car park, AMG version sits quite low and needs to stay away from high curbs."
Thanks to all for help, especially
@fabes and
@Wearsthefoxhat (you seriously need to reveal how you came up with THAT name!) who said they would go take a look
