2006 Nissan Xterra SUV SE 4dr SUV (4.0L 6cyl 5A)
Updated Long Term Review
 I purchased my Xterra in 2006 new from the lot. I wanted an SUV because I was moving to New Mexico and needed a vehicle that had very good utility, was great in the backcountry, and can get through snow on uncleared roads. My road is never cleared in the winter.  I've owned it for the entire time.  While some of the critiques I've read in the reviews have some merit, ie. hard plastics inside, and gas mileage, on the whole its been very good.  I replaced the tires at about 50,000 miles. The Driver's seat started making noises and was successfully fixed by the dealer in Santa Fe (good service dept!).  The fuel pump was replaced under warranty before 36000 miles.
