A car loses value when used because the components degrade (presumably, a new car not being driven, but stored doesn't degrade).
An apartment or house could degrade when being lived in - but that's the internal furnishings, which is "easily" replaced. The concrete, walls and other structural features degrade regardless of whether an occupant is in it or not!
A car that you bought 20 minutes ago has suffered no measurable degradation of the physical components, but has lost a very large portion of its "new" value. The lost value is purely from the "new" label which the car no longer qualifies for. That is why people will tell you never to buy a car new.
That's deprecation, and it's super fast in things like cars and consumer electronics. However, as far as I know, homes do not deprecate rapidly (ie. a "brand new" house doesn't command a significant premium over a comparable 1 year old house)
This is also true in China. Shrink wrap is left on things indefinitely so that they will appear to be new. I've seen it happen on things ranging from doorknobs (already installed on the door) to board games (opened and played, but with the shrink wrap carefully preserved to fit over the lid).
