I contacted 6 dealerships by email. I heard back from only 3 of them. Conflicting info was passed to me as to whether or not the car I want actually exists, or will have to be built. The only significance of this is the timeline.
Price was too close to call, but local trade-in tipped the scale. Well, that, and convenience.
Saturday we will double check with our local dealer that what I have in writing is true, and will leave a deposit.
I am AMAZED that 3 Audi dealerships didn't respond.
