Sales of the Model X were slow during the first quarter of 2016, the company blaming suppliers for production problems, though extremely high prices also might have been a factor. To date, I have only seen one Model X.
Like Tesla's Model S, the firm's primary product, the Model X features clean styling that carries over many Model S details on a taller body. Model X fails to some degree because its aerodynamically curved roofline reduces potential carrying capacity. A greater failure has to do with its gull-wing rear doors -- an impractical feature that happens to be related to those supplier problems noted above.
