 We had a 2014 Azera(base model) and were quite pleased with the car...but there were a few features that were not on that vehicle - mostly safety related - that I would like to have.  We found a 2016 Limited with everything that we wanted.  The driver's information and NAV systems have been significantly upgraded.  Safety features like blind spot, rear parking sensors, and adaptive cruise control are a real plus.  The 2014 is a good car, but we like the updates and the upgrade to the 2016 Limited model...well worth the value to us.
