If you are destined to break a mirror on a 210, I would strongly suggest the curb side mirror.
I did recently and walking into the dealer, three of my buddies quickly asked "Which Side??"
The curb side lists for nearly $ 100. where as the driver's is about $ 475. The latter is heated & dims with oncoming headlights.
