The Buick Invicta is a full-size automobile produced by Buick from 1959 to 1963. The Invicta was a continuation of the Buick Century concept that mated the standard size Buick LeSabre (pre-1959, Buick Special) body with Buick's larger 401 cubic inch Nailhead V8 engine, yielding what was referred to as "the banker's hot rod." The name was derived from Latin and signified 'unconquerable, invincible, unbeatable, unvanquished' according to Buick Motor Division sales training materials. The Invicta series was introduced as a full line of body styles for model year 1959. Sales never approached that of either the entry-level LeSabre or top level Electra models, but were consistent with the traditional sales penetration of Buick's sporty mid-priced models (the 1954 to 1958 Century and 1963 to 1970 Wildcat). The Invicta continued the tradition of installing Ventiports on the front fenders from the Century.In a survey of 1959 Buick owners in the March, 1959 issue of Popular Mechanics, 47.1% of owners like the ride comfort, though many (25.2%) said the drive shaft tunnel was too big. Starting in 1960, an Invicta Custom trim package was offered, featuring bucket seats and a 'consolette' in the hardtop coupe, convertible and wagon and a leather bench seat with a center armrest on some 4 door hardtops. Sales were nominal.According to Robin Moore's 1969 book The French Connection, "the 1960 Buick Invicta had a peculiarity in body construction conducive to the installations of...extraordinary, virtually detection-proof traps concealed within the fenders and undercarriage" that made it a popular model for international heroin smugglers.
