Buick Century:
Midsize Car

Contrary to popular belief, it looks like General Motors and Ford build the most dependable midsize cars on the market. Buick’s staid Century tops the list, followed by the nearly identical Buick Regal and the Mercury Sable. The Buicks are comfortable up front, a little tight in back, and nicely styled. Try to buy from an original owner – many Centurys are former rental cars.
