How do Tesla dealerships work?
Tesla does not have any dealerships. Instead, Tesla has showrooms and service centers. The showrooms allow people to go in, look at the cars, arrange test drives, and order a car. Ordering is done via the Tesla Motors website so you can just as easily order from the showroom or from your living room. The price is the same no matter how you order. (If you order at a showroom, they'll often give you free swag like a shirt and cap.)
There's no car salesman pushing cars at you so he can make quota or get a sales commission. There's also no shady finance guy or shady manager to get approval from.
The Tesla employees there simply answer questions you might have about the car, going electric, efficiency, charging, etc.... When you decide to purchase, they'll walk you over to a computer where you can customize your Tesla and order online. No haggling. No discounts. No BS.
Tesla has no dealerships. That is, honestly, the biggest reason that buying a car from them is so pleasant.
They do have showrooms where you can look at a car and arrange a test drive. There are people there to answer your questions. But all sales are made via the web site.
