Bought certified 2 years ago, Our Xterra has seen dirt, water, and 110 on it's speedometer. We had no problems driving it on light offroad courses, and it's big enough to seat 4 in the back (please dont do it though!) The MPG's aren't too good, but it's good enough for what it is. Surprised at it's speed, though, since it outsprints most family sedans to 60, and the 21+ gallon tank will last you 350-ish miles. Biggest problem are the rear seats. The front ones are soft, and big, but the rear bench feels just like that. a park bench. don't spend more than 4 hours in the back of it, or your back will hurt.
The V6's power, off road capabilities, looks, sound system
Interior could be more comfy, a 6 speed Auto box, better MPG's
