I recently bought a CLK 230 - Its a '99 and covered 120,000 Miles - Theres no history with the car, So im not sure what has/hasnt been done to it, Apart from Oil changes etc, What should I really get done to it to make sure itll be up to covering another 120,000. Cam belt change, or are these Engines chain driven ? Any advice on what I need to do would be well recieved ! Thanks in Advance.
