Purchased my AMG GTR PRO and it came with these WeatherTech Floor Liners but I haven't used them - they are in like new condition.

The WeatherTech FloorLiner accurately and completely lines the interior carpet giving "absolute interior protection"!  The WeatherTech FloorLiner lines the interior carpet up the front, back and even up the sides of the 2020 Mercedes-Benz AMG GT R’s footwell.  Digital laser measurements of interior surfaces offer a consistently perfect fit!
