Well, my engine bay is covered in protective undercoating and since I drive the rolla throughout the year, my engine bay looks like @ss. All I do is wipe off the CAI/DC strut brace and armor all the hoses, etc. A nice CF cover would be like a satin bow on a muddy pig.
If I bought it and installed it, I'd know its there and I could show it off to friends, but any judge at a car show will just pass it by.
So I am using the money on exterior trim for the moment
Actually the seller of the cover changed his mind about the direction of his engine bay as well - that's why it is up for sale in the first place.
