I'll I can say is, DON'T DO IT!!
OK, this is just my opinion, take it with a grain of salt, but that dash would look butt ugly on any color....Admittedly, I haven't seen the monstrosity in person, just in multiple pictures, but the circles on the dash are nothing short of hideous, and I just don't see how they'll match the Mini's interior. It looks very out of place. More like something for the Beetle than the Mini. Why not just have the dash painted astro black after market, or just use one of the standard dashes (anthracite would look very nice)?
