[Bill in NJ]

So I bought this car body 30 years ago and still do not have it finished. It seems like every time I sell parts the people always want to buy this body. I keep saying no but would like to know the the approx value of it is ? Most of the body work is done, new roof installed and all new glass. So what is just the body worth ? I have the running gear done and motor rebuilt and would like to finish this car in the next two or three years.
