I actually think it depends on what colour the car is..... for example, a black sunroof on a metallic pink or green car would look completely out of place (externally), whereas on a yellow car like yours, it would be excellent..
Also, if you don't have alot of black on your car, it would also look out of place...
So in other words, go for it.. nice darkly tinted sunroof, would be f@$king sweet...
