The first Plymouth came off the line June 11, 1928 and shortly after that, Plymouth parts and vehicles were introduced to the consumer market. It was the Chrysler Corporation's first entry in the low-priced field. By the time the year was out, 58,000 Plymouths had been shipped. Demand became so great for Plymouths and Plymouth parts that a new Plymouth plant was begun on 40 acres of Detroit real estate in the very same year of the company’s founding to be completed in record time, ready for occupancy in 1929.
Plymouths and Plymouth parts were actually priced a slightly higher it’s class competition, but they offered Plymouth parts such as hydraulic brakes which while standard on a Plymouth was not offered by the competition. Plymouth parts and vehicles were originally sold exclusively through Chrysler dealerships.
The origins of the first Plymouth can be traced back to the Maxwell automobile. When Walter Chrysler took over control of the trouble-ridden Maxwell-Chalmers car company in the early 1920s, he inherited the Maxwell as part of the package. After he used the company's facilities to help create and launch the Chrysler car in 1924, he decided to create a lower-priced companion car with Plymouth parts. The Maxwell was reworked and re-badged as a low-end Chrysler model; and at the end of the decade this model was once again reworked with Plymouth parts and re-badged, this time to create the very first Plymouth.
Most Plymouth parts and models offered from the late 1980s onward, such as the Acclaim, Laser, Neon, and Breeze, were badge-engineered versions of Chrysler, Dodge, or Mitsubishi models. Chrysler considered using redesigned Plymouth parts, giving Plymouth a variant, to be called the Accolade, of the new for 1993 full size LH platform, but later decided against. By the late 1990s, Plymouth parts for only four vehicles were sold under the Plymouth name: the Voyager/Grand Voyager minivans, the Breeze mid-size sedan, the Neon compact car, and the Prowler sports car, which was to be the last model unique with Plymouth parts to the brand.
Originally there were to be a number of Plymouth parts designed for new models of the vehicle brand that were meant to be launched before the corporation's big merger with Daimler-Benz AG. The first model was the Plymouth Prowler, a modern-day hot rod, the PT Cruiser was to have been the second. Both models had similar front-end styling, suggesting Chrysler intended a retro styling theme for the Plymouth parts and brand as a whole, but at the time of Daimler's takeover of Chrysler, Plymouth had no unique models besides the Prowler. Further, while all Plymouth parts and car dealers also sold the Chrysler line of cars, many Dodge dealers sold only Dodge; it would have caused much greater disturbance to the dealer network to discontinue Dodge than Plymouth. Consequently, in 2001 DaimlerChrysler decided to drop the make after a limited run of that years Plymouth parts and models.
The last new model sold under the Plymouth marque was the second generation Neon for 2000-2001. The PT Cruiser was ultimately launched as a Chrysler, and the Prowler and Voyager were absorbed into that make as well. Following the 2001 model year, the Neon was sold only as a Dodge in the US, though it remained available as a Chrysler various markets.
