In the old days us old body men would adjust some of that out by tweaking the bottom hinge. If u are not squeamish put a piece of metal about the size of a body work dolly into the open bottom hinge and GENTLY push the door in direction of closing it but dont actually close it. Do this a little at a time so u can see how much it is moving. It will move the sagging door up towards the top and forward, if u are careful.
