Go to a Mercedes dealer, and ask the shop techs who the best alignment person is.

Schedule to have him align your car front & rear to 1993 300E SportLine specs.

If you can, meet with the alignment tech, and let him know what you want, and that you will be back if he doesn't do it right.

Insist on a test-drive afterwards, and a printout of the BEFORE and AFTER alignment specs.
