At that point, I can just go to another dealer and preorder there, and hopefully get better service.
That's just not possible with Tesla. There is no dealership competition with Tesla. If Elon Musk doesn't want to sell you a car, well then you are screwed. Less competition, less customer service, punishment for bad reviews, etc.
Now, please understand that I'm a fan of the 'no dealership' model, which is why I'm highly disappointed in his reaction to the bad review. I was hopeful that Tesla would be a good citizen, and show everyone that the 'no dealership' model is a fair one, with no downsides. Unfortunately, this reaction isn't it.
