A buddy just bought a 2017 Explorer Sport and I had a chance to look around it and made a few mental notes of differences between the 16s and 17s. I thought it was interesting and you might too. The obvious difference is SYNC2 in the 16 vs SYNC3 in the 17. But the differences extend beyond that. The cupholders on the 16 have little rubber nubs to keep the drinks from moving. They work OK but not great if you have a smaller drink. The 17s have spring loaded nubs that actively press against your drink to keep it there. The 17 remembered the heated seat and steering wheel settings the next time it was started. My 16 doesn't remember and I have to turn on my heated seat or steering wheel every time. I really wish I could fix this on my 16. The 17's all weather mats have more rubber lip, protecting the carpet better than the 16 all weather mats. I think there was another difference but it's not coming to me immediately so when it does I'll update. I can't quite justify dropping the $1600 on the SYNC3 module just for Android Auto & Apple Carplay where SYNC2 seems to work OK for me.
