bought used in 2006, had it until 2009. It was a fun truck to drive. Very manageable in traffic b/c it's so short. I had only 2wd, not 4wd, so wasn't the best off-road. Despite being RWD, it still was ok on snowy roads.
Not sure why it doesn't get the press it really deserves. I think Nissan just sucks at marketing in general, but they basically ignore the Xterra too.
