I waited until now--7 months post damage--to have this minor repair done. It is being done by a Tesla authorized body shop and all the work has been approved by my insurer, Farmers. The initial cost estimate was about $5000. After the area was "opened up" the estimate jumped to $11,000 and this was ok'yd by Farmers--so all the work must be needed. If this was a non-Tesla, and if the sheet metal was not aluminum, I know the cost would not have exceeded $500 to a $1000 and could have been completed in a few days. My repair is now in its 4th week. I have been told that even though the damage is a "minor" dent in the rear quarter panel, "everything is connected to everything else" in the Tesla and many parts need to be removed and replaced. I do not know how Tesla can survive if its cars are so difficult and expensive to repair.
