I think that your not being blown away by the guitar was the real deciding factor. I think I played two notes on my shaved neck, amateur routed 68 Tele (newer electronics so only the wood was original) and knew right away that I wanted it. The 65 neck looked legit (but that decal looked terrible and the tuners were a big minus) and the body, with the remnant of the center channel and the notch might have been the real thing. So it could have been a good deal for a refinished 65 piece of wood but not if it wasn't magical in your hands. Obviously, GC knows how dodgy it looks and the price they paid was in consequence. So it was a very attractive price for a 65 Tele but only if it was a good one (and for you, it definitely wasn't).
