My own experience with having our (now-lease-returned) Model 3 backs up collision repairs being more expensive. I live a major metro that has a single repair shop certified to work on Tesla vehicles. They have a multi-month wait, and they charge more to repair Tesla vehicles than the equivalent luxury vehicle because they can.

A newer luxury SUV with an MSRP 2x of our Model 3 had a lower collision premium on our car insurance policy.
