The Z32 is really a fantastic car. Elwesso covered it pretty well on price range and where to look so I won't really get into that. A big thing to understand is the Twin Turbo was an expensive sports car, and as with most forced induction sports cars, if you get one in less than very well kept, there will be lots of little things to do (maintence, hoses, possibily turbos, etc). So make sure you can afford more than just to purchase the car.
If you have any specific questions or want to pick my brain, feel free to e-mail me at
[email protected] or say hello on AIM at NorthShoreRacing and I'll be more than happy to assist you in any way I can.
Hope to see you in a Z car soon!
