Ya,the key to working on your Z or any other car,is just absolutely no matter what,take your time. I always do my repairs and maintenence on my days off. My very first DIY`s were also just changing my own oil. Then I slowly progressed from there. And always feel free to ask any questions. There`s no such thing as a stupid question when it comes to repairing your own car,because that`s how we learn,by asking questions and gaining knowledge. I always print the pages from the TECH section and keep it with me while I`m working on my car. Good luck and I hope you enjoy your Z!
