I was rear ended at very low speed but it left 2 punctures where the license plate screws made contact with the bumper. I took it to Tesla to get an estimate and they suggested I get a new pre-painted bumper ~$1200. The certified Tesla auto body shop across the street from the service center suggested a repair instead to better blend the paint. Insurance adjuster determined repair would be covered and it ended up costing about the same as replacement ~$1200.
I found a DV Adjuster online to file the initial claim but they were honestly a nightmare. I paid ~$400 and they never inspected the vehicle but rather provided very boilerplate language to send to insurance. In their "report" they included similar vehicles with damage "examples" that all appeared to be made up. Geico, who was handling the DV claim, said that the report was useless as none of the examples had VINs or links and couldn't be verified in any way. I ended up going back and forth with the DV adjusters before finally filing a chargeback on my credit card. They also literally laughed when I asked about filing a Loss of Use claim in addition to DV and told me it was impossible.
The Geico adjuster admitted it was difficult to determine a DV since there were very few used M3's with or w/o damage for sale at the time (2019). He also said it was very hard for them to understand the impact of mileage on the resale value of EVs. He showed me how he was coming up with his number, by searching CarGurus for Model 3's with similar miles in the same metro. There was basically only one example in the country and he offered me $1000.
I continued to periodically search CarGurus for examples to increase the DV offer. He quickly increased his offer to $2k and told me it was the highest he could offer. I sent him a few more emails with additional examples before he ultimately increased the offer to $3k and said it was his final offer and we would have to go to court for the claim if I didn't accept. I spent so much time and energy that it probably wasn't worth it but I did very minimal work to get it up to $2k. If I did it again, I would spend a set amount of time looking for examples and then be done with it.
