As you say, the colour chioice is very personal however, when deciding on what colour, when looking at the black, we were really put off by a black interior with a black colour, it looked so dark and gloomy.
If you do go for black, go for a light interior (Oakham or Sussex - probably Oakham).
When we were deciding on the colour, were seriously considered the Brechin Slate but when we saw it on the road, we weren't impressed.
I'll admit to owning a Platinum Ice with Susses - it looks good and is popular because it looks good! As for re-sale, the Platinum Ice will always sell (becuase people are conservative) and I don't think there will be a flood of them on the 2nd hand market as there just aren't the volumes for a flood to occur - more like a trickle.
Cheers
