For those of you considering ordering an MX or MS, read carefully the threads in the User Interface forum. Not to dissuade you from making a purchase, we know you'll love driving your MS/MX, but so that you completely understand what you are buying. The Tesla is a very advanced vehicle in many ways, and very very behind the state of the art in other ways. If you're coming from another luxury car (MB, Lexus, BMW, Porsche, Audi, etc.) you'll need to adjust your expectations in some areas, while finding that the Tesla exceeds your expectations in others. Be an informed buyer, you'll be happier after you take delivery.
