Thanks for the response. I have rebuilt a couple of cars. 1 being my 88 mitsubishi starion that I purchased as a shell. I did all the work myself except for paint. I love driving it because there are not many clean ones around. I have even won awards at import shows before. So I understand getting pleasure out of doing the work yourself. Also, when I buy a car to restore, I cant sell them once they are complete even if I wanted to, i just cant bring myself to do it. As far as the 810, i simply have never seen one. When I purchased it, It had been sitting in a backyard for years and I finally stopped by and asked the owner what his plans were for it. So I don't know much about the car other than I think its going to look pretty cool when I'm done with it. Like you mentioned, I hear about the 510 and the Z cars but not the 810s. Just wondered if they are rare or desired as other Datsuns are.
