2006 Nissan Xterra SUV X 4dr SUV 4WD (4.0L 6cyl 5A)
Great vehicle if you need it
 I bought my Xterra with 4wd used in 2010, and have since had it for 2 and a half years. It has been a fantastic vehicle in terms of reliability and performance. The problem is the gas mileage. If you do not need to haul heavy things, pull large objects, or you do not frequently encounter bad weather, then I do not suggest this SUV. The back seat is cramped for adults, and the interior lacks a lot to be desired in terms of comfort. Combine those aspects with the very poor mpg, and it makes this SUV difficult to validate. HOWEVER... if you do need such a vehicle, I could not suggest a better one. The reliability is up there with Honda, and off road/ working performance is great.
