I could not agree more. Removing the steering wheel takes away chances of damaging the dash and/or dash cluster (especially in the C-class).
I think it should be possible to get the dash cluster out without removing the steering wheel (haven't tried it yet with my own SL) in contrary to the W107 models.
By the way, mercedes uses "loctite" on the steering wheel bolts which makes it (not always but still to often) impossible to unscrew some of the bolt. I think they are afraid that the bolt will come loose.....
