Advantages of the 2017:
- adaptive cruise control can come to a complete stop
- Platinum trim is awesome should you opt for that
- active park assist can do perpendicular parking as well
- The buttons for changing EV mode, park assist, etc are in a better location
As you can see, other than Sync3 the advantages of the 2017 only apply to loaded models. Also, I actually prefer old-school shift knobs :P
It's actually very easy to reprogram a Sync3 unit (you can buy them on ebay or from junkyards) and replace MyFordTouch in a 2013-2016 Fusion. I've done this to my 2013 hybrid and a 2015 Escape. All you need is the Sync3 unit + screen (paid $700 last time), a new USB hub (about $50 in parts, not strictly necessary if you don't need CarPlay), a Fakra GPS antenna ($15 on amazon), and the necessary wrenches/screwdrivers, and you're good to go.
4DTech and Infotainment.com will charge north of $2000 to send you pre-programmed units, but there are experts out there who will charge only $100 or so to just send you the values to program in by yourself, which is far more worthwhile.
So if you have a better deal on a 2016 just go with that and if you really want Sync3, PM me and I can help you out.
