And I think a new producer might have an effect, but if they're going to do something like that I reckon they'd need a whole new team (as Clarkson and Wilman do sort of come together as one). But replacing the trio of presenters we have now isn't something easy - they would need to get people with their own new personalities, not copies of the current three. I would say they should finish in 2 years time, leave it for a couple of years, then bring it back in a whole new way, like they did in 2002. New presenters, new ideas (not necessarily going back to old fashioned motoring shows, and not necessarily continuing cocking about, although coming up with a new image for Topgear wouldn't be simple), and a new team. But as I said, re-starting a show such as Topgear after what it has become is not going to be easy.
