The hardest part of the repair would be the side where the vent/rear of the passenger cabin is torn off. That CF shell is 'glued" to the frame and doesn't look like an easy job to remove or put back on. I wouldn't really trust a bodyshop with that work unless they're experts at CF repair and have a good understanding of the roadster's build. I saw a white roadster that was being rebuilt from salvage at Telsa, Menlo Park, and viewed that center cabin CF structure and asked about it. Just looking at that and knowing how its permanently fit does not make it an easy and inexpensive repair. Hence the salvage title. I don't think the frame is hurt from this impact.
Also its really odd how this roadster's been passed around, starting in FL, sold there, then shipped out to CA. 15K markup or so possibly for putting back on the rear bumper and lights.... also why'd they back out of repairing it? My assumption was cost, they didn't know how specialized that damage is, and with specialization / unique parts the cost is driven very high.
As for the crash, looks like it was rear-ended lightly but that pushed the roadster into a car or some other structure that damaged the side. The rear bumper-cover, lights, etc that look new appear that they may have been from the 1st person trying to resurrect this roadster and bailed due to the cost of repair.
I also noticed the CF hardtop is chipped and damaged, the front right corner. It wasn't damaged in the pics where the rear-end is off. Another problem when cars change hands so quickly amongst people.
