Looks great! Seems we had the same weekend (see my Zaino post a few posts below). I'm going to try what you did on the rims, but first I'm going to take each wheel off (one at a time), remove the brake dust on the backside of the rims (because you can see inside the wheels), and then clean the fender wells (Simple green and elbow grease). I love how the X5's fender wells are all shrouded...makes it real easy to clean.

BTW, this season's Soprano's kicks ass! Thank gawd for iControl (can't always watch it on Sunday).
