Hi folks

This question isn't intended to insult anyone, either buyers or sellers. But there's always relatively "recent" high-end bikes (say 3-5 years old) being listed at pretty high amounts of money (I'm refraining from the use of "high prices" as it is a relative term). I'm arbitrarily choosing $2000, but I think my question can even be extended to "low 1000s" for slightly lower end modern stuff. I realize all these prices are (probably) a lot less than what they cost brand new, but no matter how you spin it, 2nd hand is 2nd hand.

So for instance, will any of these (randomly selected) bikes sell?
COLNAGO VELO DE ROUTE | de route | Laval / Rive-Nord | Kijiji
Specialized Venge | de route | Laval / Rive-Nord | Kijiji
Trek Emonda - Spartacus - 58 cm - LIKE NEW / COMME NEUF | de route | Ville de Montréal | Kijiji

These 3 bikes weren't meant to start a nit-picky discussion on the 3 specific bikes themselves, and whether the components/details warrant their asking prices, but my question is whether anyone here actually knows anyone who has spent that much on a used modern bike? The only people I know who've ever spent serious money on a modern bike (i.e. >$2000), all bought them from a store. So that's my point. Is there a market for four-digit used modern stuff?

Just asking.
