When I was researching there was some must haves for me, the first thing was the 2.7 twin turbo, second thing was all wheel drive, third thing was the Revel upgrade stereo, which to me sounds better than what they're putting in the 2019, that THX surround sound takes away from what that Revel stereo sounds like in the older ones, it might have just been me and that day, but I definitely think my 2016 sounds better than the showroom 2019 MKC stereo I listen to. 4 thing is it must have the 22 position seats, and the last thing, and I think you get this with one of the packages I just mentioned, must have adaptive steering. And yes you must have the later model of 2016 that allows the sync 3 upgrade, I'm not absolutely sure but I think even the younger 2016 models may give you the sync 3 ability to upgrade through the Wi-Fi download.
