MNH meaning in General ?

The Mercury Monarch is a compact automobile that was marketed by the Mercury division of Ford from the 1975 to 1980 model years. Designed as the original successor for the Mercury Comet, the Monarch was marketed as a luxury compact vehicle; alongside its Ford Granada counterpart, the Monarch expanded the segment in the United States as automakers responded to the 1973 fuel crisis.

Taking its name from a former marque of Ford Canada, the Mercury Monarch was slotted between the compact Comet and the Montego in the Mercury model line (later, the Zephyr and Cougar). Sharing many of its chassis underpinnings with the Comet, the Monarch marked the final evolution of the 1960-1965 Ford Falcon chassis architecture. The Monarch was also the counterpart of the 1977-1980 Lincoln Versailles sedan.

In total, 575,567 Monarchs were produced. Ford assembled the model line alongside the Granada at Mahwah Assembly (Mahwah, New Jersey) and Wayne Stamping & Assembly (Wayne, Michigan). For 1981, the Monarch was discontinued after a single generation, with the Mercury counterpart of the Granada taking on the Cougar (and ultimately, Marquis) nameplate.
