Scruff Dog

I have a 1973 240Z that I parked in my back yard 25 years ago. It ran when I parked it but has not been started since. It is completly original, has very little outside rust, but now has floorboard rust. I thought that I would someday restore it, but now know I will never get around to it. I just need to get rid of it now. Any ideas as to how much the car is worth? Thanks
