The Montclair was introduced in 1955 and applied to Mercury's premium automobile line. Ford historians are at a loss as to where the name originated; the consensus is that it's taken from the upper class community of Montclair, New Jersey. For 1955 and 1956, Montclairs featured Mercury's best appointments, extra chrome trim, and different two-tone paint combinations to set them apart from other Mercury products. 1956 was the year that Ford introduced its Lifeguard safety program, and the Mercury Montclair came standard with a deep-dish steering wheel to help protect the driver from the steering column, safety door locks, a breakaway rear view mirror, and optional seat belts and padded dashboards. The dash was redesigned with a new three-tier instrument panel.
The Montclair model line also included the Sun Valley, which featured a Plexiglas "bubble" over the front half of the roof section. While futuristic cars were often featured with clear glass tops in the 1950s, like the concept car Lincoln Futura, consumers rejected the tinted glass roof Sun Valleys (only 1,500 were produced in 1955) because of the heat buildup in the interior of the vehicles. Following lower sales of the Sun Valley for 1956, the version was discontinued for 1957.
