The Xterra X is available with an automatic ($20,750). The 4WD Xterra X comes with the manual ($21,950) or automatic ($24,950).

Xterra S 2WD ($22,150) and 4WD ($24,150) have move up from entry-level to mid-grade trim for 2006. They come standard with the Power Package, anti-lock brakes (ABS) and Electronic Brake-force Distribution (EBD), air conditioning, AM/FM/CD stereo, tilt steering, eight-way adjustable driver's seat, Nissan's Utili-Track cargo system, a tubular roof rack, rear bumper steps, and 265/70R16 B.F. Goodrich Long Trail tires on aluminum wheels. The six-speed manual transmission is standard, the five-speed automatic optional ($800). Options include a Utility Package ($550) that includes sturdy step rails, a cargo net, a flat-folding passenger seat for carrying long cargo, a first-aid kid to fit Xterra's signature tailgate bulge.
