In my case, I had two estimates given to me. One directly from the Tesla collision repair center in Elk Grove, and one from Gerber. Turns out they were almost the same price.
The customer service at the Elk Grove center is the best I've had from any company, shop or store, that I've ever been to in my 34 years of life. It took a while to get in, but knowing it's done by Tesla themselves made it worth it.
Their bays are full of Tesla's but despite that, they give you their full attention anytime you need to speak to someone. They make you feel like you're the only one getting their car repaired. Updates twice a week (minimum) are appreciated.
I am picking mine up today and got a message from Charles (awesome dude) to plan on late afternoon because on final inspection he decided he wasnt thrilled abour a part of the paint (on one of the million pieces of my car ) met their high standards...and he was having it redone.
Anyways ill quit rambling, but I can't say enough about that place. Awesome team they have. Also, if anyone from Tesla comes across this, give these employees a raise...you absolutely DO NOT want to lose any one of them.
PS: my eta for the repair work was 6-8 weeks at Gerber, 4 weeks at Tesla, and Tesla finished it a week ahead of schedule
