Ordered mine, finally. Getting it Friday. Polar white.
It was either white or grey for me, I just couldn't live with that superbright orange and I'm still not sure about the care issues with that, admittedly nice looking, racing green.
As far as mode goes, I guess I'll have to wait and see. I keep my Tesla in sport all the time. I did try 'chill' once and it was horrible, like sitting on a three legged greyhound struggling through treacle. I do like the instant response of an EV so my guess is that it'll be in sport all the time as well...
