My dad had a 1995 NA Z32 for quite a few years. I got to borrow it for an extended period once, and I have to say I really enjoyed it. Certainly the NA ones aren't fast by today's standards, but the overall balance of the car was just really nice. The steering felt connected and responsive without being excessively light or heavy, the clutch was really easy to modulate, the brakes felt good, and it had enough power to feel like it was doing something when you stomped on it.
