How much could I sell this pick up for?

I have a used 1987 Nissan King Cab Pick Up that I'm trying to sell either whole or for parts. How much do you think I could sell it for? Its a little beat up and rusty but it works. Also, if you're interested and live in Colorado then e-mail me at jessebonds@hotmail.com, I'm not using this to advertise I just wanna know how much it could sell for.
