Introduced in 1959 as an entry-level Buick range, and to replace the Buick Special, the Buick LeSabre took on GM's new B-body on a 123-inch wheelbase. Under the bonnet was the 5,965cc V8 engine. Bodies available were; 2-door and 4-door sedan, 2-door and 4-door hardtop, convertible and station wagon. The Buick Series 4600 Invicta was introduced to replace the Century, and was equipped with a 6,571cc V8 engine, and could be ordered in 5 different body styles from convertible to station wagon. This was the smaller Buick built on the new GM B-body, but with the engine of larger Buicks. GM also produced a new C-body for its larger cars in 1959 with a wheelbase of 126.3inches and given to the Electra, Electra 225, Oldsmobile 98, and all Cadillacs.
