If you're on the fence at all about it, especially with it having been listed as "good" condition, I'd say a third option is to call GC and wheel and deal. Explain to them the condition was falsely advertised as "good", it's not and needs some work, and negotiate a partial refund and use that to get someone to restore it to your liking... that, or you're going to return it. Or negotiate a hardshell case or something else useful to you. While GC tends to make me want to pull my hair out, they are, at least corporately, dedicated to trying to make their customers happy. It's at the local level that they struggle with this philosophy.
PS: Love that color.
