Well, I will tell you straight, with the body looking the way it does, you will take a large loss on it. Especially if it is not sorted enough mechanically to simply blow a perspective buyer away. Needs a tune and a different torque converter....has some body issues i.e. does not look or run good to most people! Not knocking your car but I think you would be better off keeping it/finishing it then selling it as it is right now. Worst case get a quick and dirty 6 month paint job put on it and flip it quick.
