Right,
My mirror fell off of the Bora as the people that had the screen replaced must have skimped and didn't get the glass with the bracket built in and got a basic screen and bonded the mirror on.
I've tried all sorts of ways to keep the mirror on but none seem to last more than a few minutes or a few bumps in the road.
So it looks like I'll need to resort to having a new windscreen but Autoglass want £458 for one fitted

Has anyone used any other companies that could possibly do it cheaper.
