I blundered onto the British version last Saturday, while scanning the HD channels for a hoot. The episode was the one where the three of them have to get 1000 miles through Bolivia to the Pacific Ocean, using locally-bought SUVs. One guy had a Range Rover, another had a Suzuki Samurai, and the last one got an old Toyota Land Cruiser. I almost had an asthma attack from laughing, it was that good.
