2008 Mercedes-Benz CLK350 Reviews
Overall it is a great car. My only complaints are with the heating system. The auto setting does not really adjust where the heat/cooling comes out. The older C Class cars did. There are also many problems interfacing an I Pod/I Phone with the entertainment system. The music plays fine, it just does not display on the main entertainment display.
