The nameplate began as an option package for the Monterey and became a top-of-the-line package for 1975. It was not until 1983 when the Grand Marquis became its own model and took its place as Mercury's only full-size car. It stayed as strictly a V8 powered rear-wheel drive car all the way up until the Mercury brands final year in 2011. Through the long life, Mercury Grand Marquis parts were steadily updated over the years. One update was the switch from overhead valve to overhead cam engines in 1992. The Grand Marquis was a popular car in many parts of the world and used as an affordable full-size car by many groups from retirees to cab drivers. Its combination of size and smooth ride won many buyers when few other cars offered that combination for the price.
