I think the point has been totally missed by most of you.
You're paying for a quality instrument, made by a reputable company. It is a used instrument by any definition (yes, it is remove from packing, hung on a wall and played by who knows how many people), and you still pay new price (maybe a slight discount because the wiggle room is built into the pricing).
You're perfectly happy to have to make repairs to it because the dealer neglects proper care of this investment built to last a lifetime, and likely generations. I'm not talking a setup to get it to your comfort specifications. I'm reiterating negligence!
When you buy a car from a dealer, do you notice the loose bolts and think "That's ok, I have wrenches and sockets, I'll just tighten them up when I get it home", or smudges and scratches that you can just buff out?
And the Walmart reference is just ludicrous. Nothing there is made to last, to be a lifetime investment.
