Are there any Tahoes/Yukons wrapped in carbon fiber?

I would guess you are talking about the interior trim, which kits are available and yes they look awesome. They come pre cut, peal and stick (for the cheaper DIY type, which is fine), take your time and clean any surface very well before hand. Now on the exterior you can get hoods, grills, trim..but that will cost ya, but no - they don't come that way

No

If something is "wrapped" in carbon fiber, it is not true carbon fiber. It is just a look alike film.

If something is true carbon fiber, that's what it's made of, it's not a wrap
