The 2013 Nissan Xterra serves as a reminder as to why traditional SUVs weren't a good fit for family duty; built for mud, gear, and off-road adventurers, the Xterra sings a siren song to weekend warrior types and hardcore off-roaders.
Simply put, it gives up some passenger comfort in the name of all-around usefulness--and particularly, usefulness in ways that a car or crossover probably can't deliver. Although the seats in the Xterra aren't as supportive as those you'll find in some of Nissan's other mid-size or large models, there's decent head and leg room in front, and the rear bench, while a bit upright and hard, can fit adults when needed. Its best use is probably flipped forward--to down to expand cargo area.
Trims and cabin appointments in the Xterra, as with the Frontier pickup that it's closely related to, are a bit plasticky. But we wouldn't want leather or delicate trims here anyway; there are plenty of easy-to-clean surfaces. Interior noise could use more of a damper on the highway, especially in PRO-4X models, but otherwise the interior is relatively quiet compared to other off-road-focused vehicles.
