We may not realise it, but every new encounter begins with a moment of eye contact which allows us to gauge whether we are attracted to the newcomer. Even more remarkable is the fact that the first three seconds are decisive. So let's see that first meeting with the CLS again in slow motion. Second 1: the curved L-shaped headlamps of the new Mercedes face sparkle at you seductively. Second 2: refusing to give way easily, you cast your gaze across the rest of the CLS and are struck by the contrast between the restrained sides and the dynamic curve of the arching roof. Second 3: you take a step backwards and can hardly believe you eyes. This car is an extraordinarily attractive combination of a coupe and a four-door saloon - a synthesis of sportiness and comfort. Second 4: the CLS Class has won. You get in.
