I for the life of me cannot figure out what could possibly justify this valuation for Tesla. Sure, their cars are pretty great, they have a ravid fanbase, and they have a pretty entertaining CEO who excels at driving interest in the company. They would need to execute perfectly and deliver more cars to customers than Volkswagen in a few years to justify such a valuation right now, and I just don't see that happening…
The Nissan Leaf came out and was way ahead of everyone but nobody bought it because they couldn't find it. The dealers would hide the car in the back and avoid showing it to you. There was no incentive for them to get you in a Nissan Leaf because they would make profits, negligible ones, on the sale but the place they make their money is maintenance and that would deplete their profits.
The issue with this is the dealerships aren't owned by the organization so the incentives aren't aligned. If GM/Ford/Toyota create the best EV the dealer won't have any incentive to sell them until unless they make up significant profits, which means they would have to make up 5-7 years of maintenance profits on the initial sale. In essence they will just sell their land and move on and have to take a loss. The smart dealers sold their stake in the dealerships and now the suckers are holding onto the last bit hoping to get out.
The dealerships we have now Ford/GM/Chrysler/Toyota/Volkswagen/Nissan are all going to disappear, that's why their valuation is justified. The only competitors are going to be the new car companies because they will adopt the same model Tesla has where they own their own dealerships. It's why the current Auto companies and dealers are lobbying to not allow Tesla to own their own dealership.
