So CF hoods turn yellow? So they have to be painted? I'm flirting with the idea of a CF hood as well but unsure of the look on a black car and if they're too "ricey" for lack of a better term. Didn't know about the yellowing.
Cheap ones turn yellow after too much exposure to the sun because they use cheap epoxy. So if you don't have a garage and you park outside at work, etc., then I don't recommend a cheap one. It will look fantastic until it yellows, after which it'll make the whole car look cheap and, yes, "ricey". You could paint it, but what's the point of having CF if you're going to do that? You could smooth and paint a fiberglass hood and it would look just as good for half the cost. If you do go with CF, it's best to get one that has a lifetime warranty against fading, yellowing, and cracks. Which means it'll be pricey, but it'll look good for the life of the car or you get your money back.
The point of CF is weight reduction while affording a good strength to weight ratio. I would buy the best one I could and absolutely would paint it. In my opinion, CF is not a fashion statement; it has a purpose beyond that of taking an observer/admirer on a visual tour de force.
All true, but if you're going to paint it, you might as well go with fiberglass. Carbon fiber is stronger, but fiberglass weighs about the same and costs half as much. And the hood is not necessary to maintain structural rigidity.
Then again, it has been said that if you're worried about the cost of repairs, an M5 is the wrong car to buy.
