Below is another take on custom floor mats for the F10 M5
These are made to specifications and one can pick any leather and border color etc
Also the design can be chosen (ie cross or straight)
The quality is outstanding and they are all leather.
I decided to give them a try and picked black leather and color matching "brown" borders,
I also had a ///M5 logo stitched onto them.
They are produced by Inpelle (

and Sergio (owner) is very helpful and responsive
