There's a lot of over-reacting going on here.
Considering how few S550 sightings there have been in Canada vs USA, this isn't really a big deal (especially since they are definitely not for sale).
Ford Canada doesn't even really seem to have much information available yet. We still don't have Build & Price, for example. I'm guessing the dealer probably just had some kind of event to try to build up interest for the Fall.
