Tesla stores carry zero inventory. What do you think it costs to build that shiny Ford, Mercedes, Honda, you name it store? What do you think it costs to operate it? To staff it?Comparing the direct sales model vs the franchised dealership is pretty similar in the case of Macbooks or electric cars. Any retailer can't sell you a iPhone or Macbook, they need to be a Apple reseller which comes with terms and conditions. It's no random fluke that Tesla has stores that look and feel like Apple stores. Most of the overhead of a dealership is needed, in the case of a shiny Tesla store in a mall they don't eliminate the overhead and cost of storage of extra inventory, the service center, the parts storage, etc they just move it to another place.
The carrying costs associated with new car inventory at conventional dealerships is high; most dealerships have a revolving line of credit. Every day a car sits in inventory its cost increases. All these costs are passed on to you and there is no value added.
The dealership is a huge, very costly middle man. Tesla eliminates the middle man. Stores have a few cars that you can look at and test drive. These cars are sold from time to time, also online. There are few employees, because there is no management sales hierarchy to set and approve sales price. Employees only need to know how the cars work and some stats. There is zero pressure at a Tesla showroom store.
I humbly suggest people try to stop comparing Tesla as a car and a business to conventional cars and car companies. Tesla has no desire to be conventional.
