OK, I am FAR FAR FAR FAR FAR a fan of fake carbon fiber, or "carbon fiber look" products...
However, if you are going to do it, there is only one to use. That's 3M's Di-Noc carbon fiber film. I hate leading people in that direction because I feel it's for posers... but it really does look very close to the real thing, and I have been impressed with the results.
If you tell people you wrapped your interior, you better tell them it's Di-Noc, and not real carbon fiber or I will publicly shun you! LOL
Here's where you can get Genuine Di-Noc:
