Backed out too fast...the garage owned me

The mirror is cracked pretty badly, but it looks like it's still holding up it's shape. I've driven at pretty high speeds, and it hasn't chipped at all. Haven't washed my car yet or driven in the rain (i wonder if that'll do anything?)

Anyways, lookin for a replacement glass if anyone has one.

Thanks
