I had a mono wiper on my W124 and have one on my R129 ('01). They both worked quite well, IMO, and it's fun to see the startled look on a passenger the first time that single blade unparks and sweeps across the windscreen. The "bow tie" move at vertical is a picture of kinematics. Unnecessarily complex, of course, but effective and in typical MRZ engineering style, a whiz-bang detail.
It's like the pleasure I got when I realized the side mirrors on my W124 were assymmetrical; the left and right are different sizes and shapes. I was told there was an engineering reason for the difference that increased the rear vision. Whether or not that is the case, I thought it was cool that the engineers could overrule the designers.
That is what provides me a great deal of small pleasures from my Mercedes automobiles; finding a neatly engineered solution to a problem I didn't even realize existed.
