This might be old...not sure. I think they build this demo car for the most recent CES. But it is absolutely wicked! Besides the rotating seats and sliding top, I thought the rear LED-screen tailights that show movie clips every 30 seconds were pretty neat. The 295 pictures of their installation from beginning to end is also a sight to see.
