We purchased WeatherTech floor mats for the front, back and cargo area of the car. This is the 3rd set that I have purchased for 3 different cars. We had to have Brown to match the interior and the Buick set comes only in black. Mind the full set cost ~$320. The back and cargo area fit really well. The front seat mats do not, they slip side to side and there is a gap that I often catch my foot on entry. I reached out to their customer service who in my opinion is not helpful so I wrote the chairman and have yet to hear anything back nor am I expecting too. In any event I would recommend bypassing WeatherTech and getting the Buick version from the dealer. I have seen them and they fit better than these supposedly laser measured ones we purchased. That is our experience with them and in fact it will be our last experience with them.
