I had this done on my C180 elegance and the stupid dealer opened the door trims to instal the window films, but lost or broke some clips so he glued the door trims back instead of buying the new replacement clips. Did this because the clips would have to be paid by him. Had he told me, I would have volunteered to pay for them just to have it back in original shape. The trims were loose and had no contact with the door metal. Had the idiocy to say it was like that before he did anything. Never will I go back to the same place again.
