I've always disliked the Enzo from a styling point of view but I think it looks pretty good in Pearl White, so it may start growing on me after all. Just shows how colour sensitive some designs can be.
I think the cars definitely look better in FXX form - particularly the front lights. Love it in the white!
The main problem for me is that the front is just too long. It makes the car look far too nose heavy in profile and detracts from any elegance the shape may have had
