On first inspection, the owner of the body shop told me $12k to $15k. But that's when he thought he could repair the carbon fiber body panel, not have to replace it. And he didn't know about the underbody aluminum panel dent then either.
That side carbon fiber panel is huge. It goes from in front of the door to behind the charge port door, and includes all the attachments for the door, door sill, charge port door, and trunk lid.
