I think there's going to be a thriving aftermarket in upper grill garnish replacements...
- plain chrome
- plain matte black (or back grille color, to match the egg crate)
- bow tie outline (center cutaway) in both versions above
What Chevy shoulda done was put the 'Chevrolet' in reverse lettering - that way, when one comes up behind a passenger car (aka: 'lesser vehicle') to scare the bejeezus out of the driver, they'll know what's 'about to end their life' if they don't move out of the way...LOL
Unfortunately, there's no help for those side mirrors, until GM changes out the plastic. Some (real) chrome might look nice there (especially on the bottom half / base), although they'd have to get a special FAA exemption concerning reflection of sunlight toward in-flight aircraft.
Now that I think about it, chrome would add weight, so that ain't gonna happen, either.
