Honestly, as much as top gear is about cars, it is as much (or more) about the 3 blokes that muck about all the time. My wife doesn’t watch top gear for the cars, she watches it to see Clarkson tease Hammond about his height and/or teeth, and for James saying “permission to say cock” all the time.
Update: Wonderful. Now you can’t watch any Top Gear UK episodes from the BBC website because I’m in the wrong country. Balls.
