This is the big question. What does the dealership do other than sell cars for Tesla? Dealerships make a lot of their money doing regular maintenance and warranty repairs on cars. With an electric car, there is a lot less maintenance to be done. And they are much more reliable. They have an 8 year, unlimited mile warranty. No other IC engine car can offer that, because they simple aren't as reliable, and by their nature, never can be. Most of the problems with Teslas have been software bugs. Once they get all that figured out, there's very little that can go wrong. And fixing software bugs can most likely be done by the end user at home, just like they do with their computers, phones, TVs, and game consoles.
