Sometimes a very hard question to answer. If you are in love with that good ol' guitar and still want to see it live another day, that's one thing. But if the guitar is too far gone, I'll save my time and save your money. I will tell you no. Major structure damage can get very expensive. Repairs on Martins, Taylors, and the like are worth sinking $200-$1000 into it. Now, a $50-$200 starter guitar is just not worth dropping that kind of doe into it.
Just because something is old doesn't mean its a valuable vintage instrument.
