The Buick Invicta is a full-size automobile produced by Buick from 1959 to 1963.[1] The Invicta was a continuation of the mid-range Buick Century that mated the standard size Buick LeSabre (pre-1959, Buick Special) body with Buick's larger 401 cubic inch Fireball V8 engine. The Invicta continued to be the intermediate hardtop coupe, hardtop sedan, convertible and station wagon, labeled as the Buick Invicta Estate, until it was replaced by the Buick Wildcat as a coupe or sedan, while the station wagon was replaced by the Buick Sport Wagon in 1965.
The name was derived from Latin and signified 'unconquerable, invincible, unbeatable, unvanquished' according to Buick Motor Division sales training materials.
