High oil usage?
I'm burning/losing about a quart of oil per 1K miles or so...
Is this normal?
I do have the leaky camshaft sensors, but I doubt that would account for that much oil loss.
I am replacing the oil sensors tomorrow (just got them in the mail this morning) so I will have an accurate usage/loss shortly after that. I've checked the bottom and there is no oil gunk buildup that I can see.

No smoke and no odd noises when driving.
I've driven the car about 1.5K since I bought it at 70K miles.
Now when I drive the car, I always drive it HARD. I never take the CLS63 on any leisurely drives that put highway miles on it. I drive it on back roads and almost always put it in manual with traction in sport. I do always let it cool down when I am on my way back by not driving it hard, so the oil in the turbos does not get parked hot.
I'm swapping the leaky cam sensors today, so that won't be a factor anymore.
