Sounds like you need a second opinion from a MB specialist shop. I have had 3 W124 sedans.

1) Why would the front shocks be worn out in 80,000 miles? Maybe at 150 to 175, but not 80.

2) Why replace shock mounts? Are they visibily cracked?

3) Did he test the ball joints? The fact that he called them front joints is a warning sign.

4) The tie rod ends and idler bushing should be fine at this mileage?

5) What about the steering damper? This is a cheap easy replacement and probably should be done.

6) Initial vibration is probably normal and due to overnight flat spotting. All my 300E's have done this.

7) I sure wouldn't let him replace accumulators without a second opinion.

8) Finally, the other obvious thing is the thrust link member of the 5 link rear suspension. There is one link that tends to wear out and cause wandering.

This mechanic does not sound like my MB indy sounds like. I just went through a front end rebuild with him on my '92 Sportline. He doesn't replace components unless they are worn out.
