Facelifted Mercedes C-Class leaked?

Is the drawing above the the new Mercedes C-Class? I had my own doubts but based on previously taken spy shots of the car (below), I believe it just might be. True or not the drawing above might be, but we can be sure that the facelifted C-Class will have some slight changes at the front and at the back. The new car will have new headlights and front bumper, most likely be inspired by the E-Class or possibly the new CLS.   The car will reportedly be introduced at the North American International Auto Show (NAIAS) in Detroit. So stay tuned for more information.
