I sort of started my search with your ideology and found a 2015 MDX Advanced SH-AWD Certified. However, I don't need or really want the Entertainment as I imagine my child when he's old enough will be more into tablets, what not.It seems everything being equal, a used 15 MDX Adv sh-awd looks like the real sweet spot for mpg (because of 6AT), tech, safety, entertainment, and price. The 15 MDX was the last year before Acura added the crazy pricing with the Acura Watch systems. There should be plenty of 15 to pick from for the next few years if the 2016-2017 are just more money for the same vehicle.
I would take a 15 and 16 MDX of the same model for a test drive. My used 11 MDX Adv Ent looked exactly like a new 13 MDX Adv Ent and I had an $15,000 extra in my pocket.
