I've ordered mine in silver. I want something that goes well with black wheels - that isn't white!
White looks great, but is easily dirty, and I can't help feeling white is a 'fad'.
Silver is a happy medium - easiest to keep clean and shows up less marks etc. It looks good on anything, and doesn't stand out too much... and never goes out of fashion.
My ED30 was Steel Grey - which was kind of the same. Blended into the background, reasonably easy to clean...
I'd have ordered the same again, but I really want black wheels and steel grey is a bit dark for them.
Black is definately the best looking colour when its polished and shiney... but the problem is that within 30 minutes, the dust has settled, and its dirty again. I've had 3 black cars in the last 5 years - and I don't think I'd have another one in a hurry. If you get black, make sure you have plenty of time to look after it!
