The GDO is basically the same one they use at the BMW dealer, it is the same door, only the rails go vertical, and it just raises straight up rather than folding and going over the car, and uses the control panel with the "Up" "Down" and "Stop" buttons. All I know is the sucker who bought that house has to go back in the middle door to close the side doors every morning.

That said, it was built in 2000, there are more than likely improved systems for opening and closing it. I'm waiting for the force field.
