The S-class cars produced over the years have always been a reference point for elegance and style in the World automotive production. The size were also important to point out the "flagship" role of the of these recognizable German automotive production. The S-class price has always been high, not only for the choice of luxury materials but also to support the "premium" positioning on the market. Among the versions that have had great commercial success we can mention the "third generation", produced from 1991 to 1998 and the "fourth generation" produced from 1998 to 2005.
