The 1999 facelift brought forth a series of changes and line-up additions for both body coupe and cabriolet body styles.
The first received a new model powered by a 4.3 L V8 unit while it also received numerous upgrades comprising an ESP system as well as a retuned suspension and large brakes. The slightly physically redesigned CLK rolled on bigger, 17” wheels while its drag coefficient was lowered for an even more aggressive ride. Several features seen on pre-facelift versions were retained, such as the antilock brakes mated to a brake assist system as well an optional key-less antitheft ignition system.
