I traded in my 2001 Xterra XE with 108k miles for 2011 Xterra SE about 1 month ago. This is a solid, safe SUV. The 2011 is very comfy, but there are some things I wish it had for the cost: a temperature gauge, a decent stereo, carpeted cargo area (otherwise EVERYTHING slides around), power seats, multi-CD changer, Sirius radio, and - better/different interior upholstery and plastic. Even a drop water stains these seats. It didn't on the 2001, but it does on the 2011. And the plastic console collects every piece of dust because it has a softer material. It really is annoying how much it collects and retains dust, hair, etc. Drive-wise, it's solid, fairly quiet, and does well in the mountains.
Acceleration, quiet, size of cargo area, dash controls, solid ride.
Temperature gauge, decent stereo, carpeted cargo area (if you want it carpeted, you must buy separately), Satellite radio, better gas mileage, higher quality windshield wipers.
