Start with what the Plymouth Cambridge is: a 4-door sedan / 2-door club coupe / 2-door station wagon with 1951-52: 3.6 L I6, built from 1951 to 1953, at the height of the post-war boom. What it meant takes a little longer.
Where it came from
The Plymouth Cambridge is a full-size automobile, produced by Plymouth from 1951 until 1953. It was Plymouth's base-range base model in its 1951 and 1952 lineups, along with the shorter wheelbase Concord and the sole base model for 1953. It came with new features such as electric windshield wipers and downdraft carburetors when it was introduced. It also had "Safe-guard" brakes, that had two hydraulic cylinders per front wheel instead of just one It replaced the Deluxe, and was replaced by the Plaza for 1954.
Under the skin
The engine is 1951-52: 3.6 L I6; other versions carried different engines, listed in the specification table below. Drive goes through a 3-speed manual standard(1951-1953), "Hy-Drive" semi-automatic $146(1953), Automatic with Overdrive $98(1953). The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 1951-52: 118.5 in / 1953: 114 in. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.

MotorJury scores cars on the United States complaint and recall record, and the Plymouth Cambridge has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
