We are looking to purchase one of these vehicles. We went to the dealer last night thinking about the QX60, but drove a QX56 instead and loved it. We’re driving another one tonight at a different dealing. What are the differences between the 56 and the 80. We know they are essentially the same vehicle, but what are the benefits of the 80 vs the 56? i read somewhere that it was the technology, but can anyone give me some specifics? Thank you.
