I have WeatherTech floor mats in a 2006 Chevy Silverado truck and a 2013 Lexus RX350 and am very please with both of these sets of mats and they are both made with a rubber material. I was so pleased that I ordered a set including the trunk mat for my new BMW m850i xdrive coupe. When I received them I was surprised to see they were made out of plastic and not rubber. Upon installing them the trunk mat fit perfectly as did the rear seat mats. The front mats however didn't fit well at all. The sides of the mats are made to come up on the sides a little over 2". These sides were not only not near straight but they didn't fit the sides of the car floor and in some places over 2 1/2" away from the sides of the floor and door sill side floor. They also didn't lay flat at the rear of both front mats and were high in the middle causing the seat bottom to catch the rear of the mats bending them up jamming the seat from moving forward when you move the seat forward to have people get into the back seat or get something out of the back seat. So I called WeatherTech and they wanted pictures of the poor fit. After WeatherTech received the pictures they sent me two new front floor mats. This new set fit equally bad so I called WeatherTech again telling them these were no better. The sides of this new set of mats was 3" away from the sides of the floor in some places 1" in other places and touching in some places and still not laying flat in the back of the mat causing the seat to hit it when moved forward crushing the mat and jamming the seat. I was told to turn the mats inside out to stretch the sides out and flatten the rear of the mat. I said won't they crack and was told they wouldn't. So I did that! It did make the side get closer to the floor sides however the back of the mats were the same. So thought OK I'll just push down on the rear of the mats with my hand when I need to move the seats forward. The sides were still not straight however and cosmetically looking awful but I thought the protection of the carpet they offered was worth it. So I left them installed. The next morning the plastic moved back as they were and were inches away from the floor sides. So I gave up and just kept them which I shouldn't have done! I never thought of all of the dirt that drops down in-between the car floor sides and the ill fitting sides of the floor mat. It's like a funnel directing dirt down on the carpet and getting in-between the mat and the carpet. The other issue with these mats is the fasteners they send with these mats to attach the mats to the car floor mat anchors don't fit. I called them again and they sent me two different other types of mat anchors to try and those didn't work either. The factory mats have like a velcro attachment to the floor to keep them from sliding forward. So I went to Lowe's and bought some sticky back felt furniture pads. I stuck them to the bottom of the WeatherTech mats that made the mats stick to the velcro like floor attachments. That seemed to work OK other than the sticky back glue gets gummy after awhile. WeatherTech should be ashamed to sell such a inferior product for this $125,000 car. I would return them for a refund if I could. As I said the trunk mat is fine but I would return the floor mats if I could but I've had them too long so they will just need to go into the garbage!
