Well, first of all, I'd likely never accept a Martin unless it was close to 40% off MSRP.
Then I might allow a higher price if it was truly excellent.
Then, if it had something more than minor defect - recall it's a wooden product and can nick fairly easily - I'd hope for that 40% off AND excellent sound.

I purchased my custom shop OM-18 Sinker due to the tone and price. I later noticed a couple very minor nicks in the top. I thought about returning it, but ultimately kept it due to the sound, playability, and price (in that order).

That said, when I brought it up to the Martin rep (it being a Martin Event at my local dealer), they offered a nicer case as recompense. I gladly accepted and now have a great guitar with a top-notch case.
