The great thing about white is that it looks great even when it's dirty.
The appeal of this colour is that it allows you to see the subtle design details that are masked by darker colours or the reflections of metallic paint, and it contrasts with the black stuff so that the shape of the glass and light clusters is emphasised, which is a nice thing. I'd always go for a dark colour on a car whose design was a little iffy in places, but in this instance, you really want something that will bring the design details out.
I was really suprised at how in twilight, white even looks better. The glass areas effectively become black, with the bodywork picked out even more strongly. (In the gardening world, they always say to go for white flowers if you want a good twilight summer garden display!)
Just one example - the way the windscreen and bodywork relate to one another, with a thin lip coming down the pillars that develops into a deep dark sweep where the wipers live.
Another example - the subtle haunch at the back that blends as it goes forward - or the crease along the bottom of the door that fades out as you go back.
Is that enough bullsHeet about white yet?
