Hi all,
When leaving work yesterday I noticed that some moron had hit my back bumper, and left a nice scratch on it which has gone down past the primer. They of course didn't leave details, which is pretty much standard now.

I've not had to deal with anything like this before, but I am looking for recommendations as to what company to deal with the repair.
I could ask Volkswagen for a quote to repair it, but would they do a better job than say a bumper repair company like Chips Away for example? I am positive that a Volkswagen Dealership would be more expensive, but would it be a better quality than another firm? Has anyone had something similar, and any recommendations? I will take a picture and upload it soon so you can get a better idea of the minor damage. It's a Golf MK6 GT TDI 140 in Reflex Silver.
Secondly - Over winter I buckled one of my alloys by driving over one of those dreaded pot holes, and after getting my car serviced my local VW Dealership recommended I got a replacement wheel sorted as it was slightly buckled. After getting quotes for local garages for one replacement 18" Vancouver the best price I got was from where I purchased the car at £473 inc VAT. Does this price sound reasonable or I am been taken for a ride?

Cheers guys.
