Actually I like them and the one piece rear panel better than any of the other alternatives to the stockies (I call the 2000 spec stockies). But the stockies still rule ...... And the tractor company reference is a direct reference to Lamborghini - thats what they were building before Ferruccio Lamborghini and Enzo Ferrari had a war of words over quality and engineering. Mr Lambo, tractor maker, then decided to show Mr Ferrari that he could build better cars!
