I apologize if this is a common thread, but I checked the FAQs but couldn't find an answer.I just purchased a 260z, and it runs and drives just fine. The door and hatch locks however are very finnicky. I can play around with the door locks and get them to do their job, but I cannot lock the rear hatch even after using graphite lube. Does anyone have experience dealing with this? Thank you for your help gentlemen.
