Check out this super-amazing setup: a BMW M3 series, fully modded to be a full option game theater. The projector mounted in the back displays the game screen on the front window, some controls and interfaces on the dashboard. There’s a PC behind the car, and a large LCD screen next to the car so you can see what the driver is doing and how he’s cruising the circuit. You can even take a few friends for a ride :-) It’s a bit expensive to have this at your own house, but I can definitely see an amazing WOW factor if you put this on an event.
