I overheard the same thing at the dealership I worked with. A guy with a soft top wanted to order a MIC and it was coming in at about this amount. This was quite a shock as the ordering guide when having it buiit shows it's a $695 option. And those of us who ordered the original modular upgrade...
I don't know what this mysterious dealer stock you speak of is. Our store has only received our Mannequin and three factory orders. The only non-order availability I see will be from people who cancelled their orders
