It's your car, do whatever you like. I never really liked these on any of my previous cars, never had a benz before and my current W126 is only my first. When I purchased the car there was a bad dent in one of the wheel arches along with rust, and to repair it properly was not worth it. Plus I always though that pre 90 Benz had chrome wheel arches from the factory. I had seen so many on 126, 123 ,107 cars with them. So I bought a set of polished stainless steel wheel arch moldings. It covered up the blemish entirely and made my car look much better. when parked next to another stock looking w126 with out them, I think that both cars look good, either way. In my case, it worked for me. I don't think I would have installed them if it wasn't for the rusted dent. My uncle has a r107 and this was the first thing he did when he purchased it. like I said , it works both ways with or without.
