Actually I found silver to be the best colour for keeping the car looking clean. White starts to show road dust pretty quickly, especially heaven forbid you TOUCH the car; you get this little trail of black dust you had no idea was there but now you need to go over the entire car with a soft, fluffy dusting cloth to get rid of it all.
And if you use tire shine, it WILL spin off and show up as black streaks/spots if you don't wipe it off and let it set sufficiently. I've had my car professionally detailed, and even then all it took was the drive home to have spots down the side from it.
For your shift light, I'm sure these guys will make one to fit your CLS:
