The W208 CLK 55 just says CLK55 on the left side of the trunk lid and AMG in the same size lettering on the right side of the trunk lid. That is the only place on the outside of the car that it specifically says AMG.

The AMG has 342 hp and 376 ft/lbs of torque.

Main easily visible differences are the brakes, aerodynamics, and exhaust. Otherwise, it was a very modestly designed car.
