That’s a LOT of labor for a claim like this, and I think some of that seem to be possibly paint shop, for blending etc of the new mirror.. either it comes stock and gets painted or it comes painted and gets blended, and then clear coated.
I have the feeling this body shop is just putting together the claim as if it’s part of a regular ACCIDENT claim, where your insurance wouldn’t pay and a responsible party would, and their insurance.. so yeah, the somewhat reasonable or realistic additions get added up.
I’d probably try for a different shop to do it, or what about Tesla? Don’t they do repairs like this?
As others have said, a good insurer will NOT increase premiums for a comprehensive claim, and even those that do usually don’t for a year (or upon annual policy ’renewal’)
