If I remember right the Austin Gipsy had a yellow and a red lever and you could select front wheel drive, rear wheel drive and four wheel drive in both ratios, GREAT SYSTEM, pity about the other bits though.

I just bought a series 3 swb and all I have done is drive it in and out the garage, but it does make me smile , and the garage wall black. But I used to have gipsys and series ones so maybe I am just trying to recapture my youth. By the way doesnt powder where the floor should be make you...
