The 6er that I put up is a special edition with Brilliant White paintwork. At present, I understand that one can only specify Brilliant White on the 7, but I heard that its gonna be rolled-out to all models soon. Also, BMW can paint any colour - though not to the same extent as Audi - that one likes, but as Leg says, at a price!
P.S. WTF is 'AFAIK'?
