Price-conscious shoppers who do their research will learn that the Mercury Grand Marquis is one of the great full-size sedan bargains on the American market. It offers rear-wheel drive, lots of interior space, five-star crash performance, strength and durability, along with almost all the comfort and convenience features of the Lincoln Town Car -- at a much more affordable price. The Grand Marquis competes against the Pontiac Bonneville, Buick LeSabre, Chrysler Concorde, and Toyota Avalon.
