a brabus vehicle does not sport the mercedes star anywhere, not even on the steering. And speaking of a low spec brabus thats like saying Ive got a BMW 316i with M package (that animal did not exist in Germany)
A replica brabus - meaning you go to a shop to buy brabus stuff is not a real brabus. No doubt you'll have real brabus wheels and grille - but thats about it, The real deal would have a certificate on the car and its chassis no. would be verifyable as a coachworks MB.
