Hate to say it but the money you're going to dump into it will most likely be throwing good money after bad. With that much damage you're most likely better off stripping it maybe picking up a non wrecked project car (non runner from someone cheap) and rebuilding that car followed by either scrapping the rest or making a nice new lawn ornament/planter out of it. I totally understand being attached but sometimes you just have to let go.......like my Delorean..............DAMMIT
