This part is listed by BMW as BMW part number 82111469761 (82-11-1-469-761) and is described as Genuine BMW Floormats for E39 5 Series sedan and wagon, (1997-2000) in color "Titan Grey".
Sadly, BMW has discontinued this floot mat set. Because the E39 5 series has lots of black in the interior (such as the dash board and other elements) the black colored mats still look and work great in the grey E39 interior. Many customer have said they prefer the black floor mats as they show dirt and stains less, and make for a nice two-tone look. To order the black mats, please visit the black E39 floor mat set here. For full BMW fitment information or for assistance from one of our BMW experts, we recommend calling us at 877-639-9648.
