I got the UK standard Aluminium Tetragon in my M40i with the gloss black around the instrument panels. I really like the Aluminium Tetragon but am not a fan of the gloss black because it scratches and shows up the dust way too easy. Just a pity we don’t have the option to delete the shiny black around the instrument panels and replace it with something else less prone to scratching.
The Aluminium Mesh is also quite nice. It is similar to the Tetragon but has a much finer pattern.
