The reliability that is given to the buyer is the most valuable thing and I think that this gives more security to someone who wants to buy.
I say this because an acquaintance of mine bought a bike and at first glance it was excellent, but over the days he began to notice serious flaws in the bike, it had many patches in a gut, the axles were very deteriorated and although it ran well, when he went to change gears the chain jumped a lot, he found that several links were damaged, the chainring with cracks and the sprocket bent. small things that at first glance were not noticeable, but then it cost him a lot in repairs.
Thanks for the support community.
