Despite the continuous demolition of our English language through carelessness, it’s amazing that this attempt at deception slides through unnoticed.
The prefix “pre” means “before.” “Pre-dawn” hours refer to the time just before the dawn. “Pre-historic” means something which occurred before written history.
A “pre-owned” car refers to the time before it has been owned; therefore, when it is new. It does not mean “previously” owned which is an attempt to make a “used” car seem more elegant. Sorry, Marketing Fluff.
