The Buick Century was a long-running American sedan, so its name already carries a familiar image of a practical, unflashy family car. Online, short clips built around a single car reference spread because they are easy to reuse: creators can attach the same sound to a different vehicle, driveway or road trip without needing extra context. That flexibility keeps it useful for car humour, reaction edits and low-key storytelling, where a brief, recognisable reference works better than a longer explanation.
