There's a house in Clapham, south London which has a Ferrari owner. He drives on to the tarmac, presses a button and the car disappears down into the depths on a hidden lift. When he wants to go out presses a button, up it comes, the turn table moves and the car is now pointing outwards to the road! Needless to say he's a City boy. I gaped in amazement the first time I saw him do it. Unless you see it, you wouldn't know it's there, just a suburban garden.
