One of the alloy wheels on my 2008 BMW was badly gouged by a \""cowboy\"" tire shop, and looked beyond cosmetic repair.  I happened upon this business through a review in Car and Driver magazine.  They work mainly with car dealers but also offer their services to the public.  The people could not have been more charming and the service was incredible.  The damage was too severe for their mobile service, so they took my wheel into their shop overnight and delivered it the next morning.  It is like a new wheel!  All for $125.  Highly recommended!
