The star in a car thing has always been sh*t - either someone is plugging a book or a film or its someone like Jamie Oliver.. its a tea break.
Top Gear put a Reliant on a rocket, a mini down a ski slope and they pissed off all the americans. Awesome.
On the last show they drove along some random roads without really doing much. Meh.
The above mentioned are all their big events and they are al to come, some episodes in older series you never even had some, the new series every week you have some event style element to the show and then a few big ones.
We still have the car boat version 2 crossing the channel to come and that is going to be great.
