The cop car, the taxi, the mid-size sedan that was everywhere in the ’80s. It was a rear-drive, body-on-frame cruiser with a slant-six or a V8. It was simple, reliable, and tough as nails.
The Diplomat was a rear-wheel-drive, body-on-frame mid-size sedan and coupe on the Chrysler M-platform. Engines: 3.7L Slant-6 (90 hp), 5.2L LA V8 (130 hp), or 5.9L V8 (140 hp). Transmissions: 3-speed auto (TorqueFlite 727) or 4-speed auto (AOD). It had torsion-bar front suspension and rear leaf springs. It was a simple, durable car that was used as a police car and taxi.
The Slant-6 is legendary—bulletproof. The LA V8s are also stout. The TorqueFlite 727 is a tank. The Diplomat is a reliable car—it’ll run forever with basic maintenance. Rust is the main issue.
