I feel your pain as something that should be simple is now starting to become an obsession

Not through you but through your dealer.
They know the standards you are willing to accept and
they should be inspecting them carefully and rejecting any before even contemplating calling you and saying they are ready.
There is nothing worse, as you then start to question yourself "is it me, am I far toooo picky" and of course those family members round about you that you tell, are probably agreeing with you but deep down aren't interested and probably thinking "He's off his head"

Seriously though, you want the best but you need to balance it up with your sanity!
