I'd put in for either dust or high polish, and both for the same reason: they each require the body lines to do all the aesthetic heavy lifting. The dust adds nothing, and the high polish shows everything.
Really, I don't think you can go wrong either way, but I tend to agree that it's best not to stand in the middle. This thing looks nice from every angle I've seen it. Dust would look fantastic on it, and of course, there's no arguing with a high polish. The black on black in high gloss would be nauseatingly beautiful.
Also, first owner warranty?
