Or just the M Sport alloy wheel in the 3 series ... that's certainly the only car I've noticed the problem on.
I'm sure I've seen a fair few BMW's with rusty calipers etc... I do tend to believe the argument that it's a chemical reaction and I also think they probably don't get driven enough.
It's cruel not to drive a bmw hard. They are like racehorses.
