　　As it's the worst car in the history of the WORLD, we're on our travels ... to the North of England ... to name and shame the most rubbish car from a manufacturer which, frankly, should have known better. But, it's not all about hateful cars ... Oh no. You have to revel in some good ones to appreciate the stinkers.

That ends badly too.
　　We argue over the great and the awful from Peugeot, Ford, Mahindra, FSO, Alfa Romeo, Rolls Royce, Porsche, Citroen, Saab ... and many more. And we have a special, surprise fate in store for the car we
　　pick as our biggest loser...
　　Enjoy... Jeremy Clarkson James May
