You probably won't recognize it for most of the video, but the office you're seeing was made out of a 2015 Cadillac Escalade. Its builder, Lexani Motors, is calling it the "Concept One Curve." The "Curve" part of the name comes from the fact that it includes a 48-inch 4K curved smart TV. Sort of an odd choice, given that anyone who can afford the vehicle probably won't think of the TV as a particularly big deal, nice as it might be.
The vehicle is very nice though, and it converts easily between rolling office and rolling theater. We wouldn't at all mind doing our CarBuzz reporting from it.
