With second hand clothes, the important things for the purchaser are that the clothes are clean, have no tears or splits, and are fit for immediate use.
With shoes, scuffing can be covered over with polish - and if there are only minor scuffs a vendor will be wise to take that action before selling. I would never buy secondhand shoes on the net.
In all cases items must match the descriptions.
Cars - look at car dealer advertisements for how they express description. None usually would expect a second-hand car to be pristine.
