I've seen no indication there's a blacked out OEM version of the grill; I've seen some pics where it appears like they are (like the pics from the NY auto show), but I think that's just the lighting/angle. I've seen some posts here about an aftermarket blacked out Panamericana grill (going for about $1K). I'm investigating some other, less expensive options (like vinyl wrap, plasti-dip), but will only pull the trigger on those once I know it won't look like sh**. At least those options are reversible if they don't work out.
(BTW, not intending to highjack your thread, but I'd appreciate any advice, options, (polite) opinions, etc. from the senior members, sponsors on what could be done to (or what shouldn't)).
