I don't get how someone could dislike the shape enough to be physically sick.
Its a car and if any car makes you sick from the outside then you need to sort your priorities out I guess.
I love squareness on cars, hence why i love a lot of older cars rather than the new curvy shapes of the 21st Century, take the old Audi Quattro for example - The mental group B S1 looks insane, but I don't really take a fancy to the latest audi line of cars.
I also am glad about the guidelines towards aero peices on the main body - the BMW looks really clean on the side view and like a proper race car not just a car with wierd shaped bits coming from all directions.
I can't wait to see what the other manufacturers come up with!
