Actually the problem they have is that MB alignment specs after 1998 (Which can't be adjusted anyway so who cares) are specified by ride height and the height spec is based on measurement with a special electronic inclinamometer.

The only spec that can be changed without bolt kits is toe anyway so ignorance costs them. Since bolt kits can only change the spec a little less than .5 degs unless you are ready to stretch the frame there is really no reason for the knowledge of specs anyway. What matters in alignment is differences side to side and how the car drives.

All this changes with cars that have Airmatic or SBC suspension. In these cases the height is read with the Roemess tool and adjusted with the SDS before dealing with alignment.

Basically, MB used to be a very adjustable car and tires stores made their attempts. Now there is nothing that can be done anyway and they refuse
