Back in 2004, there was no Porsche Panamera, no Aston Martin Rapide, no Volkswagen Passat CC or Audi A7 Sportback. Just the Mercedes-Benz CLS: the four-door coupe that started it all. But after six years of production, the first-gen CLS has ended its production run after more than 170,000 units made and sold.

In its place, Mercedes is expected to introduce the second-gen CLS at the upcoming Paris Motor Show next month. And it'll be a tough act to follow, borrowing cues from the F800 Style and CLS Shooting Break concepts.

The final unit of the current model, a CLS 550 with the AMG styling package, is being delivered to an American customer who will undoubtedly enjoy the pioneering svelte lines of his new four-door coupe as it races its way into the history books.
