I went from a 2016 Touring to a 2017 GT. The difference between these models is huge. For me it was worth it for the leather seats, automatic headlights and wipers, and the automatic dual climate control alone, not to mention the host of other features the 2017 offers. I dont know for sure but Id imagine he 2014 GT to a 2017-18 GT is less of a leap than what I went through
