A vote for steel grey here. A biased viewpoint of course...
Still, I do really like the white & red, but on other people's cars! White looks great, but would never be clean for long - Red is fantastic, but just shouts out a bit much for me. For some reason, in the ED30 I seem to see enough gittish driving around me without a bright red car to bait them up even more!
To the OP - good luck with the saving!
