We have see from the alleged specs, that three different exterior trim finishes are going to be offered:
Dark Shadow Metallic
Carbon Flash (Black Metallic)
Body Color
Might GM also have a “visible carbon fiber” option package listed elsewhere (not shown in the leaked specs but perhaps found in other ordering guide pages that were not screen printed)?
These options made me think of what C8 body trim pieces could GM be referring to in those three options, especially since on the C7 there were exterior trim pieces that did not change regardless of what option you chose, e.g., the front grille and the lower rear fascia? I would again expect that for the C8, neither its front grille nor its lower rear fascia would change from carbon flash black metallic even if one were to choose the optional body color, or the “Dark Shadow Metallic” exterior trim options.
IMO, the possibilities for specific C8 exterior trim pieces being Dark Shadow Metallic, Carbon Flash, or Body Color include:
1. Using this rendering thanks to fvs, might we have the rear fascia upper ducting grilles change for one of those options?

2. Using this rendering thanks to Chazcron, might the rear window trim surround be optionally body colored, or Dark Shadow or carbon flash? Might additionally there be an additional visible carbon fiber window trim option?

3.The side duct trim piece, or “blade trim” is the most likely piece for changing to one of these three optional appearances, e.g. body colored, carbon flash, Dark Shadow Metallic or again, maybe even be part of a separate “visible carbon fiber” option package. We also have some comparison renderings of a couple of the potential blade trim options.


Any other C8 pieces you can think of which could change depending on the selected exterior trim option, e.g., body color, Dark Shadow Metallic, carbon flash black metallic, and/or visible carbon fiber?
