I just went to Bavauto.com and they have two sets that you can choice from. I one set I believe you can get your cars model on the mat, or your name.
Just go to www.bavauto.com
and select your year and model, then search for floormats.
O crap I just read your post a little more carefully. Are you talking about the actual carpet in the car?? I have no idea where to get that. Well now you know where to get floor mats. SORRY!!
