After having my detailer lecture me about using any sort of towel on the paint I now resort to the coin-op car wash. A couple minutes spraying those areas down does a lot, especially when the paint has been treated with a product already.That's why I like to keep a bottle of quick detailer in my vehicles with a microfiber towel.. give behind the wheel arches a nice little wipe down whenever I notice them getting kinda dirty.
As far as I know they do fit, My mate bought those a few months ago and were ok. He did that after I bought mine from China because MB said they wouldn't fit, that was December 2017. He saw how much cleaner the mudflaps kept my car doors compared with his car.Dealer says "these will not fit the car as the car has code 'P31' AMG line."
I think they should fit my 2017 GLC250d 4MATIC AMG line Premium with side step.......could anyone confirm or advise please
