Hello Danbgt,
By any chance are you in the greater Boston, MA area?
Last Friday I played a bunch of used Taylor Grand Concerts at my favorite local shop, 'Mr Music', in the Allston section of Boston. Pretty sure one of the ones I played was a 322ce GC 12 fret. If you are in the area, you might want to check out Mr Music. While they have an on-line presence, they don't list everything they have.
Good luck in your search,
Don
