31. Mercedes-Benz CLS-Class
What it is: Repeat after ze Germans, "Four-door coupe"
Complex Says: Yes, we know that the term "four-door coupe" is somewhat silly, but it's here to stay and it all started with the CLS. The swoopy, sporty, and stylish sedan set the design world ablaze and has influenced the roofline of just about every sedan that has been made since.
