My 535i is BSM and it is pretty low maintainance as far as black cars go. Keep in mind I know a thing or two about how to properly wash, clay and polish a car, but this color is much more durable than I thought it would be. I have had jet black and will never, ever, ever buy that color again. BSM is the way to go if you must have black.
