I've owned my 2013 ATS 2.0T for about 3 weeks now, love it. Stoked I found one with a manual. The previous owner had two sets of floor mats, don't know if this is normal. One carpet set installed, and a rubber set tossed in the trunk. I want the rubber set installed, but the drivers mat is missing the clips. I figured I would just remove a set from one of the carpet mats and put them on the rubber mat, but I'm pretty sure if I try any harder I'm going to break it. Are they removable at all?
