R-body
Successor Y-body

The M-Bodies were Chrysler Corporation's successor to the F-body Aspen/Volare. The platform, almost identical to the F, without the F's notorious quality issues, was introduced in 1977 and was the basis for some mid-sized Chrysler models until its demise in 1989. The M-body was also the successor to the short-lived R-body, as the Chrysler New Yorker and Plymouth Gran Fury moved to it following the R-body's demise in 1981. The M platform was the final production passenger car with semi-elliptical leaf springs sold in the U.S.

The M-cars were built at St. Louis, Missouri, with some 1977-83 production also at Windsor, Ontario and Newark, Delaware. Beginning in late 1986 (1987 models) and through the last 1989 year, the American Motors plant in Kenosha, Wisconsin was also used for production.

By 1983-84, it became clear that most private buyers preferred the equally roomy but cheaper and more fuel economical K-cars; however, the M's long-proven traditional engineering, handling, and V8 engine availability appealed to police and taxi fleets, allowing the car's continued existence until the end of the decade.
