Our MBs have that much dust too and it irritates me sometimes, more when I've just clean the cars and take it out for a spin to come back looking all grime and black at the rims.

Apparently, or so I was told, its because of the new pads MB has introduced which is softer as tkarniya noted primarily due to the fact that MB brake pads have ceased using the asbestos compound (which is hazardous to health).
