Discovery 3 used off road
Forbes has an article about which Luxury SUVs actually get used off-road. The Land Rover Discovery 3 (or LR3 as it is called in the USA) is leading the charts, with 26% of owners using it off-road, followed by the Range Rover (22.2%) and the Range Rover Sport (14.8%). The first non-Land Rover car in the list is the Porsche Cayenne with 10.5%.
So apparently I am not the only nutter using it for what it was built (or what they are marketing and selling it for). :-)
