What is your favourite Group B rally car and why?

I would have to say the Audi Quattro E2, I just love the shape of the car, the speed and agility that it posseses. Eventhough it did not dominate group b completly it is still my favourite. The E2 is still raced today in all sorts competitions including the legendery Pike's Peak Hillclimb. For a car to still be ultracompetative all this time on it surley must be one of the best race car's ever built.

What do you think?
