It needs some love If the car is solid (as in floor pans. trunk pan and frame rails) then that is a good selling point. I would spend a little time in cleaning it up and striping away the bad carpet so the pans can be seen. Take some time to make it more presentable. Degrease motor and trans and find out options that it came with. Put together a list of pluses that a buyer might be interested in. Good luck and I hope this car finds a new owner to get it back to it glory days.
