Are you talking about just the MB emblem on the grill or the whole grill. If you want to swap the entire grill then 120 in labour is a steal.
It requires the entire front bumper, wheels and multiple cables to come off. And the grill itself is horribly to unclip. You couldn’t do it in just a few hours yourself. And without the right tools and a friend to help you risk breaking a plastic clip.

The big front MB emblem is just switched over since there are just two versions of that; a normal “3D” one where the propeller blades sticks out, and a flat glossy one for cars with the distronic radar sensor behind it.
In theory the emblem can be twisted off, but I believe you actually need to remove the front number to access it from the back because the clips lock it extremely well.

 

Link below for part I’m referring to (but will be from MB dealer).

I found a video on YouTube that showed “badge removal” for various MB models. Although I’m looking to replace the trim strip and keep the badge I was hoping the trim would come off as it’s shown 47 seconds into the video on the CLS.

It unfortunately won’t on the w177 a class. As I said before, the front bumper needs to come off so it can be removed from the back. In theory you could twist the emblem off from from the front. But try to do it - it’s not easy at all and I had do get the bumper off when changing the grill anyway. And if you would manage to twist the emblem off from the front, then it wouldn’t change anything, the trim strip is an integrated part of the grill that requires the bumper to be removed. It’s not impossible though. Plenty of guides and videos out there.

 

You’ve convinced me. Sounds a lot simpler to pay the £120 and let them take care of it.

Thanks for help.
