If you get the 2017 Limited it has nicer seats and interior materials. Also has different led lights instead of the round fog lights and has 21 inch rims. If you get a regular QX70 there is no difference. That is why i just bought a 2014 QX70, did see the need to pay more for the exact same thing. I also wanted the aero front lip and it wouldn't work on the QX70 Limited. The 2015, 2016 and 2017 also have the sport QX70 that comes with a black grill, side fin is black and roof rails are black. They have a nicer interior with purple stitching. All models have the same engine and power and dash and infoitainment
