100k out of a set of rotors is pretty impressive. Obviously, some of you guys do way more highway miles and way less stop/go than others.

This makes sense now the more I think about it. There are literally almost no rock chips on the wife's X3. Put that together with the condition of the rotors, and the 42,000 miles on the clock, and clearly it must not have seen many highway miles.

I appreciate all the feedback, guys! Interesting stuff.

I was pretty to happy to find out the brakes are relatively inexpensive to replace. Now, the two leaky front struts... That's a little different story.
