Tried the online configurator for color options:
BMW USA,
BMW UK and
BMW Canada all seem to contain the same color options.
For the i4 M50, none of the colors appeal to me.... and the color I want ("Arctic Racing Blue" that looks so nice on the M440i) is nowhere to be found.
Does this mean I am out of luck? Or will I be able to somehow custom configure a color for the M50?
