Just watched episode 5 and found it one of the better episodes so far. Getting past half way without having the 'stars' come on, and I thought they had dropped the feature, sadly not.
I wonder how much Clarkson & co got paid to plug the Alfa Romeo,

because it looks like a very flawed car.

They do seem to have a thing for Alfa's. If you are going to race cars, and spend so long showing the race, I think you should say how much one car was faster than the other, which they didn't do. Sometimes the times are everything to them.
Not sure I'm too happy about what they seemingly did with the animals, even in jest, especially when the whole sequence proved nothing.
