I've driven around for two years with a dent/scratch on the driver's door and a non-folding mirror. No functionality other than the folding has been affected. When the accident happened, I didn't even contact my insurance company, just got some estimates from the then-current Tesla approved body shops. At least $3000 and three MONTHS to fix, IF they could get parts right away. My BS meter was going off, and I walked when the guy told me it took 2-3 weeks to calibrate the sensors on the door. I've been driving for two years. Yea, the car is no longer perfect, but when it's dirty you can hardly tell there's a scratch.
Get several quotes, some from non-approved body shops. Until insurance companies catch up to our realities, it might be best to wait to fix it.
