I have driven the Brabus at my dealer. First the exhaust is no different than stock, the tail pipe has been relocated to a twin center outlet. No difference in sound. The only difference in body panels is an added trim strip around the rear wheel opening. The wheels look great but didn't drive much different that any other car. It seems that the demos are not going to have the 3 or 4 extra options ie. alarm, fogs, DRL and in the Passion, the radio 10. The only changes in the interior was the grayish trim pieces are the same silver as the air outlets. No B on the shift knob or brake lever handle. The Brabus model is around $ 3000 more, but if you were to make your own from the parts catalog, it would cost over $ 8000. That's my review.
