Loads of classic owners seem to complain about the crappy standard mirrors and some replace them even without rust.
My dealer advised I change them when I picked up my car because of poor adjustment.
It's such a cheap easy fix for MMC and would improve customer satisfaction at a stroke.
Why are they prattling about with bikes, while ignoring something as daft as this problem - we should not be discussing rusty, piss poor mirrors in a nearly new car.
You know it makes sense!
