Mercedes-Benz CLS-Class Spy Photos Emerge

New spy photos have emerged showcasing the next-generation Mercedes-Benz CLS-Class undergoing a bit of fair weather testing.  Unfortunately, the four door coupe is heavily masked with plenty of false panelling, so distinguishing its various design elements is still an impossible task.  Parts of the front grille, headlights and tail lights, are however, a little more clear than they’ve been in the past, revealing a few subtle hints about what lies in store for the model.
