location of van

I've been looking at the Transit vans for some time and will likely buy a 12 passenger wagon in the next year or so. Obviously, I'd like to sit in one and take it for a test drive. My local dealer doesn't have any and said they likely won't be getting any.

I can look on inventory.ford.com and find XLT's in my region, but how do I easily find where they are so that I can drop by and check one out in person? Is there a key code on the window sticker or is there another website that lists the specific dealer? (I bought my 2012 F150 in Washington state and the Ford dealers in the NW had a great website that listed everything.) I'm in Wisconsin.
