I am new to the forum but not new to the Infiniti ownership. I just bought a 2017 Infiniti QX80. It replaced the previous model QX56. I also used to own a G20, I30, and a I35.
The new QX80 seems to be quieter and smaller. My 2006 QX56 was the top of the line loaded SUV, while the new 2017 is the very base 4WD model. I do miss some features, but I also enjoy the quietness and the more refined interior. Rear captain seats don't have arm rests. I just removed the center console to allow a walk - through to the back seats.
I think I got a decent deal on it. I sold my old QX56 really cheap, under 5K (It has 160Kmiles and 0 issues).
Hope to participate here.
