There were plenty of people who doubted Mercedes' ability to successfully combine the looks and drivability of a coupe with the practicality of a saloon. But the CLS didn't just impress all those who saw it, it inspired an entire new class of rival cars, including the Audi A5 and A7 Sportbacks and the Volkswagen CC. This is the second generation of the car. It gets a bold design and a range of efficient and powerful engines. Under the skin, the hi-tech suspension system improves the car's handling and comfort. As well as being a great car to drive, the CLS is fantastically well built and has a beautiful cabin. What's more, Mercedes offers a huge range of optional extras, so you can tailor the car to your exact specification. Watch out though - going wild with add-ons can significantly boost the purchase price.
