They sell gray market cameras...the 6D they sell is made in Japan, same place same qualitfy control, but it was meant to be sold outside of the US so they don't have GPS or Wifi built in. Some countries are strict with that for some reason, good ole US of A, land of the free home of the brave. Those cameras also do not come with a warranty, and if it breaks, ur forking out pocket money to fix it. Although i've heard stories of Canon USA servicing gray market cameras.
Here's the catch, when you call them, they'll say there are only US models left, and the price goes back to what we all see them as, 1700 being the lowest i've seen so far. I would've absolutely picked up a gray market 6D body for 1259, but it's only there to bait you to call and they'll switch you to the USA models which is more.
