For 1969, the Mercury model line underwent a significant revision, with the Montclair repackaged as the Monterey Custom trim level. An all-new chassis made its debut; sedans were based on a 124-inch wheelbase, Monterey station wagons used a 121-inch wheelbase (alongside Ford station wagons and sedans). Following the expansion of the Marquis to a full model range, the Monterey was the base-trim model range, offered as a two-door hardtop, two-door convertible, four-door sedan, four-door hardtop. In another revision, Mercury station wagons were no longer a separate model range, with the Mercury Commuter renamed the Monterey station wagon.
