Hi Jon - I'm the owner of the LCR you parked next to at Inters09'.
My wheels were refurbed by The Wheel Specialist and they have branches all over.
I used the drive in drive out service. Dropped my car in at the Tysley Rd branch at Birmigham at about 8.30am and collected the car at about 4pm.
Cost me £244 incl VAT which is more than some places but there is no hastle with you having to get tyres off etc, they do it all

City Centre is minutes away, we went shopping, cinema etc while it was being done.
Ps I have some pics of your motor from the show. I can post them up, thought I'd ask rather than hijack your thread.
