Andrew's forfour was there last week and the week before. He had an A service done too, plus new speakers, new gear selector module, new rear screen*, new poly belts and a new wheel. Belts (and wheel of course) were chargeable. *When the contractors fitted the rear screen they broke the clips on the tailgate top/spoiler and Bristol have since fitted a new one, minus the proper spoiler. It's going in next week to have that fitted.
Andrew's car has only done about 10,000miles from new and he cleans it every week, plus its had about 4 Merc valets recently so it should look at its best. The only flaw at the moment is the paint on the "powered by BRABUS" badges (he paid a lot of money for) is peeling off. Need to email BRABUS and moan at them.
