We get Top Gear out here in Australia, but they're problem several seasons behind. The las episode I recall was when Clarkson, Hammond, May turned average cars into Aqua cars. It didn't turn out that well.
Love the show and 'The Stig'.
In the new series, still in production, they take the very same cars/boats and attempt to cross the English Channel from Dover to France.
Trust me when I say it's worth watching
