yeah would love to see Sakhir orange on the M5, when I googled it only an M6 popped up and it looks stunning! orange on orange may be a bit much though.
I think I would have to go with White exterior and orange interior or orange exterior and black interior. Not having a standard metallic white though would push me towards Sakhir orange exterior. Have not seen that color in person but all the photos make it look like a reddish orange (compared to the brownish orange of Fox Red leather). Wish they had a CF roof option on the M5 as I think it would make the orange look even sharper (like in the photos of the M6). wonder if they tried making the M5 with CF roof and it just didn't look right or something...
