Buick Century is the model name used by the Buick division of General Motors for a line of upscale performance cars from 1936 to 1942 and 1954 to 1958, and from 1973 to 2005 for a mid-size car. The model name Century came about when Buick was designing its first production automobile capable of reaching a speed of 100 mph. The British referred to going 100 mph as "doing the century". The executives liked the Century name and it stuck. Keyless entry remotes are available options for most Buick Century trim levels and are a standard feature on all newer models.
