The upshot of this is that they looked at my car and quoted £1240+VAT to correct the paint and apply Gtechniq, too much for me, as they had already done the wheels and interior I have asked them to wash it and it will be £300. The wheel refurbish is £437, so that's still a substantial £737! ouch. He said my car looked good apart from some minor swirl marks, so I'm happy with that. Incidentally I had a call from Lepsons saying two of the wheels need some more work as they have grooves in them, picture below, not sure how this has happened, unless it was part of the manufacturing, they said it looks like they have filler in them? I bought the wheels new in June 2016 and have never been damaged, apart from superficial kerbing, but I always though the rear wheels looked a different colour to the fronts. When I pulled up at Lepsons on Monday, the first thing the tech said to me was that the rear wheels had been refurbished before, I said they cant have been as I bought them from BMW new, so I know the history - but maybe they have been damaged and repaired in Germany before being shipped?
