The CLK is a juicy source of profits for Mercedes-Benz. It's marginally cheaper to produce than an identically equipped C-class sedan-with which the CLK shares its underpinnings-and yet it sells for about $10,000 more. That math finally has caught on with the competition. For example, the upcoming Audi A5 coupe/convertible is based on the A4, the two-door BMW 3-series cars will be priced more like a theoretical 4-series, and the second-generation Lexus SC will be GS-based but positioned between the GS and the LS. There is no doubt that the increased competition will cut into the CLK's market share pie. In response, Mercedes plans to fortify the next CLK with several advanced technologies currently found in the S-class, including Presafe II, night vision, Comand II, and the Distronic Plus adaptive cruise control system. Mercedes also will treat the CLK to all-new styling when the third-generation model is introduced in the summer of 2008.
