I absolutely love my Xterra. It is comfy and stylish. I love how sporty it feels. I also love how well it is in the snow. (But then again when your used to a three quarter ton 99 ford ranger it doesn't take much to beat!)
Even though it is slow, the running 4wd.
Make the sun roof a slider. Mileage, and make things like oil filters and drain pan easier to get to. I have a hard time changing the oil on it because of the skid plate.
