It appears that each dealership got 2 - a coupe and a cab - for display purposes so people could see what they're ordering. Now that all of the slots have been filled and Brabuses are starting to be delivered, some dealers are selling the demos, and that makes perfect sense to me. Keeping the cars on display when no one can get them is just going to tick off potential customers, and telling them they can't even by the demonstrater isn't going to help. I'd rather get them out of there. The dealer gets the money, two happy customers get cars, and you avoid hurt feelings and aggravation.
