Most people can't afford a Tesla... so thats a moot point.
Not long ago, one could have argued that the dealership model was the best you could do. Now it's impossible to argue that, since the best car-buying experience out there doesn't involve dealers.
I'm not in love with the dealership model but its not a choice for 99% of buyers.
I didn't say just go buy a Tesla. I said that Tesla is the best way to buy a car. I didn't say it was an option for everybody, and "the best way" doesn't require it to be.
