The current generation C-Class comes with three levels of equipment - Classic, Elegance and Avantgarde. An AMG version of the C-Class will follow suit in time to come. The Classic and Elegance models (pictured below) has the traditional Mercedes Benz radiator grilles with the three pointed star bonnet emblem.
The Avantgarde version has a more sporty front radiator grilles with three horizontal bars and a large centre-mounted star. (see picture below). This grille is similar to the sport coupe models including the CLS-class 4-door coupe-sedan.
