It is time that I am interested in purchasing a Tesla Model X. However, due to pricing, I am looking for a used vehicle in the California or Nevada area. I have been doing some research for the past month and I still get confused about what version is what, so I am asking people on the forum to please try and help me out. My questions: 1. How can you tell from browsing the internet if a Tesla Model X 100D is Long Range, Performance, Performance w/ Ludicrous or even Standard? (Without contacting each dealer) 2. Have there been known maintenance issues with any Model X's/ Is it easy to maintain? 3. Why do the car selling websites have minimal information on Model X's? Are there sites that help compare the models easier? (Such as if it has autopilot) 4. Is there a better way to find 2018-2019 used Tesla Model X's for sale? Tesla's website goes from 2016 to 2018, and has a very small selection of 2018's. Would also love to hear feedback on comfortability. I am in a stage where I am deciding on a sports car (Mercedes Benz C63 Coupe) or the Model X. If you have been in the same boat or even own the car, I would love to hear your feedback.
