I see older discos and a few defenders ocasionally. Usually a more yuppie thing, but they are out there. I can almost hear them bragging about their offset differentials over their moaning about parts breaking. They tend to pick trails that are challenging to stock suvs, but seldom venture where modded jeeps and toyotas go. They seem quite competent on mild to moderate trails. But as I noted in another comment, hard trail use might not be practical, but this feature would make a noob trail diver twice as effective just by placing the wheels where you want them during the 2 times a rover is actually offroad.
