Well that was a crappy day! It's not easy to make out the damage to the bumper but judging from my experience last year, that's at least a new wing and, if it's more than the scratch that it looks like, possibly a new bumper as well (the clip fittings are easily broken apparently). That said, all my damage was being covered by insurance so new parts all round was the default. On the plus side, the headlight looks OK but you won't know for certain until they get inside. Whatever, I suspect the bill will be more tha the valet car park guy would be willing to pay out of his wages.
