My Mom bought her Maxima there, pretty good experience in general. Service department are pretty good people, its all about the salesman you get though because the few times ive been there, i can walk right by a few salesman outside smoking their cigarettes and theyll give me a look and not say a word. Other times sales people will start up a conversation no problem.
But yeah if you know what sales person you are going to (assuming you go to the one midori suggested) you should have a pretty good experience.
