And how is some bike newb that can't fit themselves, or know to switch a stem, going to know a bike ship is "one they can trust"? You might as well tell people to only fly with an airline they "trust".
And obviously, I meant "the otherwise perfect bike", now you're just being obtuse. If I spot a bike on Craigslist, that's exactly what I'm interested in, in minty nice condition, in my size, for a killer price, but the seat isn't comfortable for me, then for all intents and purposes, that bike can still be reasonably described as "perfect" for me. Having to change some piddly part in order to make it literally 100% perfect for me, doesn't invalidate the point.
