Same here, 530i saloon in Tanzanite is due to production at the end of October.
I had a chance to drive and see this color in person, it is just stunning!
Car ordered with full spec with sunroof, hk, hud etc.. And red calipers
I think they contrast the best with Tanzanite.
PS. I wanted to get Laser lights as well but they are barely visible (just some blue stripes) + they don't give any real benefit. Unless you drive in full darkness in the woods.
