Seeing as it's for your 17 yr old daughter I wouldn't bother with a c/f hood unless the current one is in horrible condition. You could probably find an Impreza hood for way cheaper. I also looked at the Seibion c/f hood you speak of and was mostly worried with how the vents are right above my intake filter (aftermarket K&N Ram Air). I would also be worried about rain and stuff getting into the engine bay, sure the engine is built tough but a few years of extra element abuse could deteriorate some parts or at least dirty it up easier.
