You sometimes feel Top Gear could happily ditch its usual mix of supercars and celebs and concentrate instead on madcap trips across foreign lands - like this one, in fact. For their Christmas special, Jeremy Clarkson, James May and Richard Hammond travel to the depths of Bolivia. The plan is to drive from the heart of the Amazon jungle to the coast of Chile, but as usual they've equipped themselves with the kind of ropy old bangers guaranteed to provide breakdown related grief: shabby 4x4s bought from local small ads for a few grand. Preview DVDs weren't available but, if it's as entertaining as previous trips to Botswana and Vietnam, it'll be a blast.
