2012 Mercedes-Benz CLS-Class

Mercedes-Benz calls the CLS-Class a coupe, but it's actually a 4-door sedan that's considerably more curvaceous than most sedans. It's also part of a growing group of models that are curvier than traditional luxury sedans--including the Audi A7 and Porsche Panamera. But while both of those other models come with hatches, the CLS-Class has a trunk. For many shoppers, the relative rarity of the CLS-Class is a selling point; it looks like no other car out there. Performance is another reason to pick the CLS-Class; with new twin-turbo V8s, it performs even better than before with better gas mileage. And there are also a number of tech firsts in the CLS-Class, including the world's first LED headlights.
