Solid Versatile Truck for a Good Price

dallas70, 09/30/2014
2010 Nissan Xterra S 4dr SUV 4WD (4.0L 6cyl 5A)
Owned for over 4 years and 52000 miles before trading in last year. Rock solid performance and reliability... I wish I had kept it. I'd say it provides more capability and livability for the price than just about any other 4x4 SUV. I paid $23,800 after rebates and I think the only area of the Xterra that reflects the bargain price is some of the interior parts (seat material, hard … plastics, cargo area plastic not as tough as I'd like). We made many family trips and commutes with this SUV in all conditions and the only thing I would have done differently is go for the nicer PRO4X model.
