Datsun/Nissan owners are their own worst enemy they only talk price down never talk price up, read any Japanese forum for any Japanese car for sale, it's always bandied around that "he" will never get that price it is only worth $...?
It's time people talked up investment value in Japanese cars it is an education process that is why gtr xu1, gt falcons & monaro, 2 door falcon coupe, mustangs, the list goes on is why these cars are pulling those dollars. People talk them up!
People are buying them like art work for future investment it is up to us to educate and create the Japanese market some people who have Japanese cars are to embarrassed to put them on the market for what the car owes them because the Japanese car community strikes it down, all cars cost similar money for ground up resto ' s and some hugely more, like anything you invest in you need support of the market place values, this starts with you this is also why sometimes it is hard to insure your car for what it is really worth, like an r100, prince gt, nissan silvia csp311, Honda 600/800, datsun 1500/1600/2000 sports, isuzu bellet 1600gt, & 240/260z to name just a few there are many jap classics I have not mentioned that are built like a watch, praise them up for change bring them in to automotive discussion of technical advances for their era not to mention equipment levels ....lynton
