The Terracotta appears to be similar to the Hazelnut, at least in pictures. and that was only available with certain paint colors also.
I am hoping that some of the MKZ's start showing up locally since it appears that they are using similar color combinations.
And I'm with you brucelink, I'm not really fond of the ebony or dark interiors. It will come down to which interior or exterior I prefer to live with I guess.
