Does it bother you that Mercedes calls it's 4 DOOR CLS SEDAN a "coupe"? - mercedes cls coupe

Is this not the same as calling a car with a large roof opening a "convertible"? It's like the Porsche Targa, which is not a Targa roof only a sunroof! When was replacing the marketing sense? Am I the first to say: "The Emporer has no clothes! The CLS is a sedan!
= 2-door Coupe
= 4-door sedan
