Matte black, noooiice.
You could get grabber blue on the previous model Mustang too, it's that enamel bright light blue.
You can also now get them in that pearlescent cream colour they use on the Mondeo's but I don't fancy that one.
A solid milky cream white would be cool, not that it would look good, it's just for the sake of a proper colour throwback to the Mustangs from the 60's.
