I have had more problems with this vehicle than all seven other vehicles i have owned combined. Granted i did buy it with 100k miles on it, none of these things should be going wrong with a Mercedes Benz. I have had U-joints fail, bolts on both sides of my front suspension break twice, electronicsgo out on the center dashboard, three ignition coils fail, and the A/C compressor has gone out. Aside from that it has a rough ride like riding in a sports car without the fun. Much of the car uses cheap materials that can not hold up to everyday use. It does have decent performance for the size vehicle it is, though.
The person you bought it from beat the snot out of it. I bought a 1999 ML-320 seven years ago that had 84,000 miles on it and just sold it with 180,000 on the odometer. None of the issues you cite happened to my vehicle.
