Mercedes-Benz AMG models are not just about the hardware – how else would the Joneses know you bought the top-dog model without the subtle exterior and interior modifications that mark every AMG product?

Unique wheels, tinted taillights, and two sets of chromed twin-pipe exhaust outlets round out the changes on the outside.
