Ran one on my 88 Z31. Couple of thoughts on it... Drains very slowly compared to the regular plug. Not a big deal but takes a few extra minutes to drain. The valve always concerned me, I was afraid it could fail. Never leaked a bit though. It allowed easy oil changes without lifting the car as I could just slide a pan under and flip the valve. Not sure that the Z32 has enough ground clearance to do this though, I usually drive mine up some wood ramps...
