I had the Model X for over two years and loved it for its styling, doors, wings, space, and speed. What I didn't like was the software had many issues with it, I was left stranded twice on long trips away from home. I never even got close to getting the range displayed once I charged it. Their customer service is really bad with the one parroted answer to all my various issues, "It will be fixed on a future firmware update." So far my Air GT has had its issues, however small and I love driving this car. I'm zkhan2 at the Tesla Motor Club forum if you want to read some of the issues that I posted about.
