I always watch it because usually the people who I have no interest in or have never heard of turn out to be the most interesting (Kevin McCloud for example). I also don't care whether they like cars or not bcause Jeremy has full taking-the-piss-out-tragic-car-histories options with some of the really clueless people. I'm not so keen on repeat performances though, there are loads of celebs who would do TG without it being a little boys club where the same people come back more than once. Also I liked Eric Bana but I sensed that everything 'interesting' he had to say got cut in the edit for being too rude... just a feeling.
