The Mercury Grand Marquis and its twin, the Ford Crown Victoria, are two of the oldest models still being produced for the U.S. market. However, the Grand Marquis continues to be a viable product for the Ford Motor Company. It remains popular among full-size sedan buyers, it’s the only standard V-8-equipped model in the segment, it’s still rear-wheel drive, it has a very large trunk, and it can seat six people in true comfort—all giving legitimacy to Ford’s decision to continue producing the Grand Marquis. It’s also the best-selling Mercury model ever, with almost 3 million units sold since 1975.
