The Century is Buicks midsize 4 door sedan. A model with a long and storied history, the Century first joined the Buick lineup in the late 1930s to emphasize the cars advertised top speed of 100 mph. Century became Buicks top seller in 1999, with an increase in sales of more than 24 percent over the 1998 sales year. I would highly recommend this car, its big enough for a family and still gets great gas milage!
