Is that what you mean by complete? The only way to get the list complete in my book is for every VIN to be associated with a person/location/condition. And for that to happen, every owner with a 300ZX (or multiple 300ZXs) need to add themselves to the registry.
But if you had actually READ the information on the pages I linked instead of being a smartass: [ http://www.az-zbum.com/cgi-bin/z32registry.pl ] says: "It is a complete listing of every single VIN number for every single Z32 that was bound for the USA over the 7 year run."
