They do, although, I believe its referred to as a Falcon door. Gullwing doors typically don't have the double hing a falcon door has. It's actually what makes the Model X door more remarkable than what a gullwing door would have been. As a falcon door with a double hing, it allows the Model X to open/close with considerably less space on either side. The swing path is greatly reduced compared to what a gullwing door would be. Not trying to hate, but merely comment on the wonderful engineering design thought behind a falcon door over the more traditional gullwing.
They do everything to my knowledge, I have an S, however.
I believe they handle all service needs
Not sure, I would think so
