No rust at all. It's been a great truck, and as the last of the "Japanese made" Pathfinders it has a lot of life left in it. The interior is in excellent shape, and the leather seats still look good.
The OME springs were from the early production and sagged over time. I added Fluery spacers and have been quite happy with those. It also has a Fluery skid plat up front. Although I thought the automatic transmission seemed more suited for a mini-van, I appreciate it much more over my 2017 Tacoma six-speed automatic which is always hunting for another gear. The All-Mode Transfer case also leaves a little bit to be desired, but I found that turning off the VDC in tough conditions gives it a little more self control, especially in slick snow/ice conditions.
I've owned CJ's, Scouts, 4Runners and Tacomas over the years, all built for off-road, and always thought the Pathfinder stood up to all of them, if you appreciated the limitations of an IFS. Plus, it has room in back for gear and the dogs:
