dont orget the manufacturers tried to bully clarkson too. the original topgear was a more sober affair, but it had JC. now, he destroyed vauxhall(general motors) or ford, i cant remember, and they refused to give cars to TG, then they had to allow after the bad publicity JC gave them regarding their protectionist attitude.
anyway, rover tried to stop the TG boys from review their "citycar?" that was made in singapore i think and they just got a rental and filmed it by secret camera!
same with the enzo, they borrowed one from a guy that got to buy it.
but you can only get away with it if you have a large audience, and that needs charisma!
