The Dodge Monaco is an automobile that was marketed by the Dodge division of Chrysler Corporation. Introduced as the flagship of the Dodge product line, the Monaco was introduced for the 1965 model year to replace the Custom 880, then later joined as a sub-model of the Dodge Polara. During its production, the Monaco was offered in several body configurations, including two-door and four-door hardtop sedans, four-door sedans, two-door convertibles, and station wagons. Upon its introduction on September 25, 1964, for the 1965 model year, the Dodge Monaco was intended to compete with the Pontiac Grand Prix in what came to be known as the personal luxury market, but ended up filling in for Dodge in the full-size, luxury line instead. The 1965 Monaco was based on the Custom 880 two-door hardtop body. The Monaco received special badging, different taillight and grille treatment, and a sportier interior with a full-length center console, as well as a 383 cu in (6.28 L) 325 hp (242 kW) V8 engine as standard equipment. Larger, more powerful engines were also available as options. The Monaco competed with the Ford LTD, a top-of-the-line model in the Galaxie 500 series, the Caprice package for the Impala Sport sedan, as well as the 1966 Plymouth VIP model for its Fury series and the Ambassador DPL offered by American Motors. These models provided competition for mid-priced sedans like Chrysler, Oldsmobile, Buick, and Mercury.
