The interior dimensions are identical to the 128/135 so the standard 1 series floor mats and trunk mat from the dealer fit perfectly (same goes for other interior accessories). I think they're actually also made by Weathertech but could be wrong. Either way they aregetting the job done. I hate worrying about keeping my carpeted mats clean and those orange stitched ones are far too pretty to step on. I'm considering having them framed for display
