here's a site with Broyhill info and a question/answerforum. It might help you.
The big question is: do you love the size, the style, the color of the wood trim? Have you picked out a fabric that's special to you and that you can't find in a ready made sofa? And if you were to buy new would it be a similar quality piece of furniture with the same frame construction? Remember that a great upholstery job entails more than just flopping on new fabric. Many times the piece is literally rebuilt saving only the frame. It would be like new.
Or would you be able to find a different style of great quality and perhaps arrange for your own fabric to be used, thus creating a custom piece.
Best wishes, KB
