I have a 2000 year Mercedes A Class 160 Classic. I have owned the car for the last 5 years and in that time have only recorded 13,000 miles (35,000 in total). I have now been told that I need the whole of the Steering Column and Steering Lock replacing. In addition to this both the rear Trailing arms are worn and also need replacing. Are these known probelms to this a class - like the Drop Links on the front??? Please help, because I can't help thinking I am being ripped off!
