Lots of comfort and lots of room

Trenton Cogdill, 01/14/2017
2014 INFINITI QX80 4dr SUV 4WD (5.6L 8cyl 7A)
I bought new in 2014 totally loaded. I am 6 ft 6 in tall and this is the only luxury SUV with adequate headroom without tilting the seat back. I have taken 5 hour trips with 4 adults and two children in total comfort. Voice operated navigation is great. Absolutely no mechanical issues in 55000 miles. I am 71 years old and this is by far my favorite vehicle. Better than Cadillac, … Mercedes, and BMW that I have owned.
