Gutted for you mate. The previous owner of my car managed to kerb 3 of the wheels in the first 5months of the cars life.
Which alloys do you have, and would it be possible to post a pic of the kerbing?
If its not that bad, then a refurb would probably return the wheel to 'as new' condition. I had three of my wheels refurb'd at my MINI dealer's bodyshop for £40 a wheel.
The result was pretty good considering mine are polished, if they had been the normal finish version of the R99's (i.e silver finish on the alloys like the 17" Bullets) I dont think I would ever have known they were orginally damaged. But because of the paint used to create the polished effect a 100% match was not possible, one thing is for sure though is that they look 10 times better than they did when they were kerbed.
Like I say though if you have a normal finish on your wheel I reckon they should be able to sort it for you without pretty much no evidence of it ever have being kerbed

If your dealership cant do it, ask them for the name of the company who they get to repair alloys before their cars go onto the forecourt.....
You may have some luck with a local firm, I dont know of any in Scotland, but I'm sure someone else on here will do. I have heard good things about a firm called laptab which is based in Birmingham, maybe as a last resort you could have the wheel shipped to them for the repair.
Good luck with it and hope some of the above might help...
