I'm a student too, but I also am a dealer brat and selll cars when I'm not in class. So let me tell you that dealers are out to make money. a lot of the time the techs that dealers have are unable to work on our cars (Which is tough). So they need a lot of time and maybe more than one tech. I would find yourself a certified Nissan or ASE tech and get a good price. Good luck with everything and take care of her. Use this sit whenever you need help, it's your greatest z32 resource.
