z33 and z34 (I guess that is the name of the new body style), because I have had problems with dealers knowing anything but the basic mechanics of the the z32. It has been roughly 15 years since they had to deal with any warranty work on the z32, so unless they have a large 300zx following in the area, a lot of dealerships do not follow the technology of the z32 because of the cost associated with keeping current.
