Question: Was the Mercedes-Benz E-Class, the coupé and convertible versions of the fourth generation Mercedes-Benz E-Class automobile or the Mercedes-Benz CLK-Class the series of mid-size luxury coupés and convertibles produced by German car manufacturer Mercedes-Benz in two generations, sold from 2009 to 2017?
Context: The Mercedes-Benz E-Class (W212 and S212) series represent the fourth-generation of the Mercedes-Benz E-Class range of executive cars, including sedan (W212) and station wagon (S212) configurations.  Sold from 2009 (as a 2010 model) until 2016, it is the successor to the W211/S211 E-Class models.  Coupe and convertible models of the E-Class of the same vintage are W204 C-Class derived and known as the C207 and A207.  A high-performance E63 AMG version of the W212 and S212 are available as well since 2009.  In 2013 (for the 2014 model year), the W212 was comprehensively facelifted, likely the most expensive mid-life facelift in the history of the automobile. The Mercedes-Benz AMG C-Class W203 DTM is a Touring car (DTM) constructed by the German car manufacturer Mercedes-Benz.

This Long-Wheel-Base version so far is only available for the Chinese and Indian Market.  Standard length versions are referred to as W213, which are also available in the Chinese Market. The Mercedes-Benz CLK-Class is a series of mid-size luxury coupés and convertibles produced by German car manufacturer Mercedes-Benz in two generations.  Although its design and styling was derived from the E-Class, the mechanical underpinnings were based on the smaller C-Class, i.e. respectively based on the W202 and W203 platforms of the C-Class.  It was positioned below the Mercedes-Benz CL-Class and SL-Class, but above the SLK-Class.  The CLK name derives from the German "Coupé Leicht Kompakt" (or Kurz), translated Coupé-Light-Short.  In 2009 Mercedes ceased to use the CLK designation moving the segment designation back to E-Class Coupe/Convertible instead, as it had called this specific line of its vehicles previously before the CLK moniker was introduced in 1997. The Mercedes-Benz E-Class (W213 and S213) series represent the fifth-generation of the Mercedes-Benz E-Class range of executive cars, including sedan (W213) and station wagon (S213) configurations.

The car was available in two body types: Sedan and Estate (Estate models were sold in Canada as Wagon).

Sold from 2009 until 2017 by Mercedes-Benz, the C207 and A207 replaced the previous C209/A209 CLK-Class models.  Like the CLK-Class predecessor, the C207/A207 E-Class are derived from the C-Class.  Sedan and station wagon models of the E-Class of the same vintage are built on their own platform and are known as the W212 and S212.  The coupé and convertible share a more aggressive, swifter look than the sedan and saloon, with a more svelte front and a sleeker bonnet. W124 is the Mercedes-Benz internal chassis-designation for the 1984 to 1995/96 version of the Mercedes-Benz E-Class, as well as the first generation to be officially referred to as E-Class.
