Interesting. Everyone has their own tastes, but I am really enamored when the design/style and the utility of a component really marry up perfectly. For example, on so many of the Pininfarina styled Ferraris, the beautiful bodywork always has some sort of function, such as aerodynamics or air intake scoops, etc. I hated seeing the Ferrari 355 which has a completely useless front grill "just for show" because we are used to having front grills on cars. Likewise on the Model S, while the front nosecone is far from my favorite styling point on the car, I can't think of something better -- putting some sort of air intake looking grill just would make me cringe (unless it provided some sort of utility).
But then that's just me. I like the look of the mesh grill in the thread above, but the non-utility of it would make me cringe if it were on my car.
