I went in talked about what my options were, this was November, so the 6MTs weren't out yet. I was advised that ordering was the best way to get a 6MT once they started making them. I left that day saying I wanted to order but I had time and I didn't want to seem to excited. Then I found the deal and brought in the paperwork then next time I went in and then ordered the car.
So if that's what you're going to do I would print it out and bring it in when you were ready to order but if they have sold a S w/ 6MT they sure as hell could give you the invoice price.
