Towards the end they converted a Renault Espace into a makeshift convertible, then drove it through a safari park, braving lions, and infinitely more dangerous MONKEYS.
Then they drove it through my local car wash, where they all nearly got mangled to death in an explosion of soap and metal as the roof collapsed.
It was just about the funniest thing I've EVER seen on television. Since they drove a car off a ski jump, anyway.
Cars are crap, Jeremy Clarkson is crap, Top Gear, though, is BRILLIANT.
