I had this “Aha!” moment recently when I visited a Tesla TSLA+1.56% store and saw its cars’ power train. It looks just like a skateboard — basically a flat slab of metal (which houses the battery), four wheels, and an electric engine the size of a large watermelon. That’s it — the Tesla has only 18 moving parts.
 Wall Street nowadays is going gaga over the stocks of auto dealerships (especially after Warren Buffett’s Berkshire Hathaway bought Van Tuyl Group) and automakers. I am in the minority in thinking that party will come to an end. Just like Tesla, Apple is not going to be using a dealership model to sell its cars. Just as with the iPhone, the company will want complete control of the buying experience.
 If both Tesla and Apple bypass the dealership model, the GMs of the world will be at an even larger competitive disadvantage. They will have to abandon the dealership model too. Yes, I know, selling cars directly to consumers is not legal in many states, but if the U.S. Constitution could be amended 27 times, the law on car sales (which is an artifact of the Great Depression) can be amended as well. The traditional dealership model is unlikely to survive anyway, as its economics dramatically degrade in the electric-car world. A car with few moving parts and minimal electronics has few things to break. Consequently, electric cars will need less servicing, throttling the dealerships’ most important profit center.
