You should do a search on the forum. There are quite a bit of owners I've noticed that have went with the Sakhir Orange interior (so it might not be as an exclusive color as you might think). Personally the color is not for me but to each their own.
You might want to start with the
Official F10 M5 INTERIOR Photo Thread and then move on to the
Official F10 M5 Color Photo Thread to give you an idea of the color combos.
If you've got more time, you can search the
Auto Gespot Website for European M5 sightings. They usually list some interior shots of various colors.
