Does it have a clean title, paper work and log books for the airframe? See FAR's 47.31, 47.35 and 47.49. If it doesn't I would not give you anything for it as you would have a hard time getting the paper work required. If it does have the required title and paper work, change the title over to your self and you have a " licensed " airplane.
As to what it is worth ??? Gary may very well be on the high side.
