Selling a car seems to be so difficult!!
Just another example. Another member has a 73 Dart Sport 340 in TB3 Super blue, white interior. Non original motor but its the correct year 340. He has all the big parts, all the correct # parts for it. It needs a patch in 1 quarter panel. $4500obo takes it.
Yes it needs a lot of small stuff but once someone starts working on your it will need the same stuff.
My suggestion is to start by lowering your price a few thousand or better yet, keep it and restore it for yourself.
