have you ever gone to merc service center with your chassis no, only to be told that it's a blue coupe with no fancy bits at all, dont worry smart never recorded these cars for what they are!!!
the cars started life as ordinary production 80hp roadster coupes which were then given to Brabus to be given the exclusive RCR/Brabus treatment.
Some Merc dealerships who have never seen one of these cars, may tell you the car is an ordinary 80ps roadster coupe - because when they look up the cars history on the Daimler Chrysler computer system that's what they were when they rolled off the production line (ie., prior to their Brabus makeover).
