Fair price for poor condition, Phase III GT

I came to own a 1969 Phase III GT Corvette when my father passed away, my grandmother has confirmed that she has documentation to prove the validity of the car. It is in poor condition (Very Poor) but I have three people interested in purchasing it. What is a fair price? It does not have the original engine or transmission.

It is Chevy Comp. Orange with the Black single stripe that goes from the hood scoop to the rear and wraps around the rear.

Similar to this car.

Seats and dash are in ok condition, but the carpet had to be taken out. The passenger door is not original either. It needs a ton of work. I am willing to sell it because I do not have the finances to restore it, nor do I have the know how.
