Hi, Can anyone share their experience of BMW OEM floor mats or floor liners vs Weathertech's? I have a 2015 535i xDrive and looking to purchase floor liners (more so than floor mats). I have seen some posts that the BMW brand liners are nice as well as Weathertech. I have also seen some posts that say Weathertech is the manufacturer for the BMW OEM and then again I saw posts that say Weathertech is NOT the manufacturer for BMW OEM. Anyone have any good data on the difference or can validate who manufactures the BMW OEM floor mats and liners?
