Hey guys, one question I've had that I haven't found a definite answer to (because something really minute could be different that I don't know about) is if there are any mechanical differences between the 08 and 10 550 M Sports? I know the 2010's come with the M door sills, M footrest, M steering wheel, and anthracite headliner, which are all just cosmetic. Are the changes only skin deep? Thanks in advance

 

One major difference is thar the 2010s come with the new hard disk-based iDrive/nav as opposed to the old DVD based nav.
