Got my '07 Xterra used in April 2010 and has 38K miles on it as of now, if it's possible to actually be in love with a vehicle - I am! Love it, fun to drive, feels solid and so far has been very reliable. I live in Arizona, so we have pretty extreme weather here, from broiling heat to freezin cold. Only thing done has been battery replaced (that's normal for AZ as batteries do not last more than a couple years here) and the front sway bar gaskets replaced. Otherwise, this truck is just awesome. I've owned many vehicles and this is the first one that make me feel like I can drive it for the rest of my life.
Solid feel, quiet on the road, handles great, VERY good road manners for a truck that has such great offroad capabilities.
Wish it got better gas mileage. Standard heavy duty shocks on all models instead of just offroad models. Improved standard stereo.
