About the Mercury Grand Marquis

Introduced in 1975 as the flagship of the Mercury line, the Grand Marquis represented the final peak of unapologetic American automotive excess before downsizing took hold. While the 460 cubic-inch V8 had lost its high-compression muscle car edge due to emissions regulations, it provided effortless low-end torque to move over two tonnes of steel with silent authority. The car was marketed for its 'Ride Engineered' chassis, sharing its 124-inch wheelbase and many luxury appointments with the Lincoln Continental. Today, it is a quintessential collector's choice for those seeking the ultimate 'living room on wheels' experience from the malaise era.
