My own opinions/perspective on carbon fiber are:
1) It's not pretty and makes no sense as trim: people use it for the high tech look but to me it looks like grey-laquered burlap.

2) There isn't a lot of weight to be saved with carbon fiber body pieces compared to cheaper options
-stock (steel) hood for a Camaro 56 lbs including hinges, etc.
- aluminum hood for the same car 38 lbs "
- fiberglass hood (with ram air box) -16lbs"
- carbon fiber hood (no ram air) - 11lbs "
The real bargain here is the fiberglass which cuts39 lbs, the carbon fiber cuts only another 5 lbs.

3) Carbon fiber makes incredible sense when you use its strength it has phenonmenal tensile strength, so in racing bicycle spokes, etc., you use both its strength and light weight. In a car, building the basic frame, or "tub" from CF makes good sense, but you have to design the car from scratch to utilize CF's unique material qualities: if you took a standard 'vette frame and structure and just converted it to CF, you would have a very light car but also one that felt like it was made of rubber - very flexible. You'd have to redesign that basic structure with boxes and braces for strength. You could end up with a very strong, very lightweight structure, cutting maybe 100 - 200 lbs, but only if you start with a fresh design.
