Our parking situation is that we park in an Apartment/Condo parking space along our building. We have an overhang, which is great in the winter with the snow, and the post for the side of the overhang is on the passenger side. The person on the driver side has a habit of parking on the line or partially on our side of the line. This habit is annoying but we haven't been too out of shape about it.
So Jen parked REALLY close to the pole one day because of the encroaching neighbor car. When she backed out later, not remembering that she parked close the last time she parked and that she needed to look in her mirror, so she hit the pole. Mind you only the passenger side rear view mirror was hit so it was way better than it could have been. That side mirror was dangling when I was at work. I came home and disconnected the wires which was the only thing left intact. Jen wasn't mad or shaken up, just extremely embarrassed. I think that stuff like this happens to everyone.
Anyways, I spent all day the next Saturday gluing with epoxy glue all the pieces back together and fixed it. I was very proud of myself. Especially that I took the entire thing apart to get under the mirror, something my fix-it dad has not been able to do without breaking the mirror. There are not many pictures because until I fixed it, Jen was too embarrassed for this to be posted, but once fixed she thought that I should be proud, which I was, and post it. These were the pictures I sent to my dad to get his advise on the direction I should go.
As you can see, it broke off completely.

I took a picture deep inside because that arm above attached to that white thing deep inside. I was trying to figure out how to glue that on deep inside. Luckily I figured out how to remove the mirror.

This glue was a miracle worker.

This is the end result. I was rather proud of myself. It didn't fit perfect but I think the molding was a little bent so it fit well enough.
