1969 Cuda A57 4 speed Whats it worth ?

Im in the process of trying to buy a 1969 cuda A57. I will try to give as much info about the car as I can, so you can make an informed opinion. First the documentation. The owner has the fender tag, 2 build sheets, and the original bill of sale. He is the second owner. The car is numbers matching. The motor, trans, rad support, trunk, its all there. Now the condition, the car is a 4 and needs to be restored. However, the uni body/frame rails are excellent, the inner fenders are good, doors and front fenders seem good. The problems with the body are mainly in the rear quarters and the paint is horrible. Let me mention this is an A4 car with a vinal top. The interior is in fair condition and with some elbow grease it could be good. The seats are not all torn up. Again, it is a 4 speed console car. Im looking for solid opinions on what a fair price to buy this car is. Let me know if I forgot anything. Thanks Lou
