If you look closely at the video, that MB had it's front control arm removed/swung-out from the top in order to have clearance to use the Hazet tool, and to have enough swing in the lower control-arm to clear a compresed spring.

I'm 99% sure that there isn't enough clearance on the W201, W124, W126, W123, and R129's to use either of these tools, and it would mean loosening the front strut and lowering to down via floor jack.

If you do the above, you don't need a spring compressor on a W124, although I heard it's hard to get the front strut back in.
