I recommend buying a silblade wiper blade, although bosch are probably the best when you cant get a silblade. I had bosch up until I learned about these SILBLADE wiper blades, all silicone, etc.
Has great blades, they last like 5 years, I have had them on my range rover for nearly 5 years already and they are perfect. I even used them on Ice. I made a 300 dollar order to buy them for all my family and friends reciently.
You can pick all kinds of colors, etc, they even have a winter blade out now.
I got one for my brothers C36 and it didnt fit so good though, but for the w124s they fit fine. Im going to talk to the company about the C36 blade. For some reason the C36 has a weird offset on the wiper blade, it doesnt attach in the center of the blade...oh well, w124s are fine.
