I've had my Model S since October, 2014 and love it. It's the best car I've ever had and Tesla's support has been excellent. But I'm not so sure about their authorized partners. I've two experiences now and the experiences have not been that good. The first was their recommendation for an electrician to install our charger. The job seemed pretty simple. Tap into the junction box inside the garage, run wiring up the wall, over the ceiling and down to the wall next to the garage doors. Tesla recommended Woodson Electric which came out to the house in Naples, FL and after inspecting the situation gave us a quote for a flat $2,000. My husband thought this was far too expensive and called another electrician, Custom Electric. They did not know we had already received a quote and after inspecting our garage gave us a quote for $425. A few days later Custom Electric installed the charger which took about 1.5 hours. Their final bill was $415.00 and the work seems excellent. My next experience with a Tesla approved-partner was after I had a minor fender bender in which the left rear door and panel were damaged. My husband told me that aluminum is hard to repair, but to me the damage looked pretty minor. See the photo. Tesla recommended 1st Class Auto in Pompano Beach, FL as an authorized Tesla body shop. This was a two hour drive for us to deliver our damaged Tesla. To make a long story short, the repair took over two months with negotiations between 1st Class and two insurance companies as well as delays getting parts from Tesla. What amazed me was the final bill, $21,199.44. This is more than what we paid for my daughter's new Chevy Sonic that she got for college graduation. Seems really exorbitant to me. Yes, the insurance company paid most of this. But these high charges are going to raise all of our insurance costs. I don't know if our experience was unusual, but it seems to me at least some of Tesla's partners are really over-charging their customers.
