1973 Dart H Code value

I figure SOLID but typical rust, Dusters at bout $1000-1500. A bad roof is way not solid. The H code is worth ? ,a 4 speed car is worth ?
#'s I have owned ???? many 68-70 B bodies ober the deacdes, I think I have fond maybe 3?? out of 50? #'s cars. People drove them hard and broke them. I had a 69 383 Runner a bd fond for me, had been in his conty since new, he knew all its man owners, He knew it had maybe 6-8 engines in it over its life. But so happened the last owner had fond and rebuilt its original engine. This is a rare occurance. Seldom do you find an HP engine to be in its original body!
The question that should be asked on these project is not so much is it worth?? $500 or $2000, BUT what will it cost to put it back together, get it on the road, and maybe restored to some degree.??????
People on her and every where else sells off a project or restored car, and they hate to tell what it actually brought!! So it is hard to have any real comparables.
