The U.S. version of the show did an off-road challenge last night. They had $5000 to buy an off-road vehicle, and they then had to get from Death Valley to Vegas without touching pavement for two-thirds of the trip. I found the episode highly entertaining. I'm sure it'll be on their site under Full Episodes in the next week, but if you get a chance, check it out.
