The Buick Centurion is a full-size car built from the 1971 through 1973 model years. Replacing the Wildcat as the sporty iteration of Buick's three full-size car lines, it slotted between the LeSabre and Electra in the lineup. The Centurion name was inspired by a Buick concept car, the name coming from that of an officer in the Roman Army. The car's emblem was not the traditional Buick tri-shield, but a side profile of a centurion.
The Centurion name was first used on a Buick concept car in the 1956 Motorama. It featured a red and white fiberglass body, airplane-like interior design, a fully clear "bubble top" roof and the first backup camera in place of a rear-view mirror, although it was never shown to be functional. This car currently resides in the Sloan Museum at the Flint Cultural Center in Flint, Michigan.
