The short-lived Centurion was already out for the two model years as of 1973. The idea of this model was to have a sportier car marketed between the LeSabre and Electra. The base ’73 engine was a 350 4bbl Buick V8, but you could still get the 455 Buick V8 optionally. Transmissions were the Turbo-Hydramatic 350, and Turbo-Hydramatic 400 respectively with each engine. For ’74, the Centurion was dropped.
