The Buicke LeSabre was first introduced to the public in 1959 by General Motors. The first Buick LeSabre’s were full size vehicles and it was considered for a long time as the entry model in Buick’s luxury line of cars. It had the lowest base price of all of the Buick models. Before its arrival on the scene, the Buick Special occupied this position. When the Buick special was discontinued the LeSabre was the replacement. The Special name however would see a comeback in 1961.
Between 1959 and 1971 Buick LeSabres were offered with a manual transmission as well as an automatic one. The three speed manual transmission was very rarely ever sold on the car however. People were just beginning to experience automatic transmissions and the LeSabre came with the Turbine Drive automatic transmission, power steering and power brakes so this was this package of choice for most consumers.
In the late 1960′s Buick introduced a new Buick LeSabre 400 package. This was upgraded trim version of the LeSabre that included the Super Turbine 400 three speed automatic transmission married to a four barrel high compression version of a smaller V8 engine. The displacement for this particular engine was 300 cubic inches. For the same time period Buick also offered the the standard two barrel low compression v8 only with the Super Turbine two speed automatic transmission.
Throughout the seventies General Motors made quite a few changes to the LeSabre. These changes began as early as 1970 when the LeSabre 400 trim model was discontinued and was replaced by the three speed Turbo Hydra-Matic 350 transmission for cars equipped with the 350 cubic inch V8 engine. This new addition was known as the LeSabre Custom 455 and replaced a base model known as the wildcat.
The seventies also saw Buick add a convertible to the LeSabre lineup. By 1975, the LeSabre came as a coupe, two sedans and a convertible.
