No one as of yet makes a headliner for the C7 that I've seen. The C6 liner is probably similar in shape and likely could work, with perhaps a little trimming. Another possibility is use an opaque vinyl decal on the interior surface. It would keep the transparent top look from the outside, yet be more like the carbon tops inside. I think the 3D carbon look would be a sharp one to go with! Or maybe something to match the exterior color of your car. And as deep as the tint is, I really doubt you'd see any signs of the adhesive through it from outside.
