MB alignment requires a veteran tech. familiar with the product. Most alignment shops won't take the time to do a total alignment. It can take an hour and a half to two hours to adjust all 8 possible adjustments. I find that I need to add one half of a degree more caster to the right front to compensate for road crown. The other important thing to notice is that mercedes requires 20 to 25 lbs of pressure between the front inner faces of the front tires to set toe. If all specs are in tolerance and even on side to side adjustments you should be happy with the results. I think at 93k your rear links should still be O.K. however they still could use an educated eye. Good luck!
