I am wondering why their website (Lincoln) is outdated as well. You can build a new MKX but it's buried in the future vehicles link. I have yet to find a 2016 MKC build and price.
The Lincoln website does have concierge chat and it was popping up automatically when I went to the site. I chatted live with them a couple times a few months ago trying to get info about MKX and black label and sync 3 for MKX (which it unbelievably does not have) They didn't know too much but said the website would be updated soon. That was over a month ago. They asked me if I wanted them to send me brochures of the 2016 MKX and MKC. I said sure (would like to see colors) and they never sent it! I went to site the other day to see if 2016 MKC was out and no of course.
