Shall I upgrade my 2014 Innova to 2017 Innova?

[jackchen]

Hello. Im own a 2014 Innova G Diesel MT, and overall Im satisfied with its driving dynamics, ride quality, suspension, and total cost of ownership.
Kaya lang I always wonder what is the difference of the 2017 Innova in terms of driving dynamincs, ride quality, engine response and overall performance. Meron po ba dito na naka experience na nitong dalawang models, at pwede po pa-share ng inyong inputs.
Malaki po ba ang difference to the point that you will advise to upgrade (or to even own the 2 vehicles). Pwede po paki-elaborate and explain ang experiences nyo.
