In my opinion, if you own one of these spetacular cars, are contemplating owning one, or just have an interest in them, you are "Missing the boat" if you are not a member of the "Registry".
There is a wealth of information available that will make your ownership a pleasurable experience.
The knowledge from members is astounding! Always get intelligent and helpful feedback on any question, and try to add my 2 cents worth if I can.
Not sure how many ZR-1's are still out there, but I would surmise it is considerably more than the 560 or so current members. (I know some of you guys have more than 1!)
Worth every penny, and you get a T-shirt !!!
