I believe that Hunter also makes the alignment machines for Mercedes, but the alignment machines are specially altered to work with Mercedes only.

Further, when setting the front end alignment, you also need a special tool called a spreader bar to properly adjust the toe. The spreader bar is a spring loaded bar that forces the front wheels apart with 90 - 110 Nm (66 - 81 ft-lb) of force. The use of this spreader bar allows the alignment to duplicate driving conditions by preloading the rubber bushings in the suspension.

The use of a spreader bar is the only way to get an accurate front end alignment.

Thus, I'd take my car to the dealer, or a Mercedes service and repair facility that has the right alignment equipment and a spreader bar.
