I've been very lucky on many fronts in my life. My luck started with being born in this country and continued through being born into my family. However, for this screed I'll stick to the Z world. I started getting paid, $125.00/week, to be a mechanic at a dealer in 1970, talk about luck. I very quickly realized that paying close attention/noticing things were important aspects to becoming successful at my craft. When I opened my now closed shop in 1980 a trickle of unmodified original owner Z cars started to flow through, talk about luck. It didn't take me long to understand the importance of documenting as many details as possible. The results of my appreciation are a large stack of photos of the many fine details of 240/260/280 construction. I also have many sloppy pages of notes describing the fine points of construction and differences between model years. My goodness, I even have several pages of notes describing, in detail, the fasteners used to secure a 240 timing chain cover for production date X. Every time a serious customer approached me for a restoration I would ask, in detail, exactly what he/she wanted the finished product to look like. Before they had a chance to answer I would describe what an original Z looked like from the factory and I'd often show them a few pictures from my collection. The answer was always not just no but HELL NO! They wanted pretty. What does pretty mean? Modern, often 2 stage, paint that has been wet sanded and buffed to near perfection. Powder coated suspension and all the other bits and pieces of modern restoration required to satisfy a customer. To see 2 of my last 3 Z car restorations visit my site and click on Customer Profiles. When a 240 left the factory there was orange peel in the paint in random places. Have to mention that this particular problem improved markedly in about 1975 or so. However, there was often a serious problem with the clear coat discoloring when 2 stage paint was used starting about the same time. The paint on the bottom was applied very unevenly and often contained dirt in random places. Most of the grommets that were glued in place had glue running down from the grommet. The suspension pieces were painted a sloppy and uneven satin black. There was overspray on some of the exterior engine components that were in proximity to the engine block. The list goes on from there. Please don't misunderstand me, I'm not criticizing Datsun, that was the way cars were often manufactured back in the Olden Days. I can all but guarantee that if a real factory-like restored Z showed up at a convention a trophy would not be forth coming. Now to address the hyperbole that has crept into the world of Z restoration. "Frame -off Restoration", "Rotisserie Restoration", "Factory Restoration", etc., etc., etc. There are some new ones now like "Magnificent" and so forth. The situation is often made worse with fancy photography and lighting. This is what happens when marketing geniuses get involved. Remember the Z Store Program? H@#$, now I'm often confused and don't understand what they're talking about. ALWAYS look at the car you're considering or send someone like me to have a look before making that offer. I understand that I've only lightly covered this subject but there you have it for better or worse.
