What is a good condition Subaru GL worth on the open market? It sounds like an opening to bad a joke, but this is a serious question. Just because the GL isn't a high dollar classic doesn't mean it isn't worth something to somebody, and there are certainly more overly restored 911s than nice condition GLs in the world.
