In my opinion (even though if a car does have the AMG bodykit/alloys/exhaust etc. BUT no the engine) it is NOT an AMG and therefore should not be badged as one... Clean debadged look is far better and shows that owner does not have an "inferiority complex..." Stealers should be shot for "modifying" badges on cars that they sell (and believe me the Salesmen do this for teh customers to keep them happy...)
Brabus are very strict on issuing badges and I dont blame them...
