The dynamics of the front end on the W124 appears to apply some pressure outward on the front of the tires. This may be true of any car, but at least on MBs, this requires the spreader bar to get correct alignment while running. Believe me, it makes a difference! The TE is almost completely oblivious to crosswinds -- the only thing you feel or hear is the wind roaring across the sunroof! The 300D wanders all over the place, but I have to replace the left side torque link and thrust linkd, so I will wait until then to do a 4-wheel alignment.
