the best choice. 

I'm not just saying this because i've ordered a GTi but i honestly think the front splitter, side skirts and back bumper look better un-painted. The contrast between white and black looks awesome.
I've provisionally ordered mine in Diamond Black but seeing that i could almost be tempted to change my mind. The only thing stopping me is that my last 3 cars have all been white and fancied a bit of a change.
