2007 Nissan Xterra SUV S 4dr SUV 4WD (4.0L 6cyl 5A)
Not as good as you might think
 I purchased my Xterra as a dealer demo.  Shame on me for not doing more homework on both the Xterra and the dealer.  While I have had a great deal of fun when taking the Xterra off road, I drive it mostly on road and have experienced nagging, little issues with the vehicle, that after doing a bit of digging find to be very common in the Nissan line. Fuel sensors and emissions issues seem rather common.  Brakes wear is terrible.  There are numerous rattles & squeaks as well.  If you are in warranty, most of these are a non-issue, out of warranty they are pricey and don't waste your time contacting Nissan for warranty assistance, one of the worst experiences ever.
