Plymouth was an automotive brand originally founded by Walter Chrysler on July 7, 1928. Up until the 1990s, Plymouth was a high-volume seller for Chrysler Corporation and one of the most profitable automotive brands in the world. The Plymouth brand name was also synonymous in the muscle car era with hits like the Superbird and Hemi Cuda (via Motor Trend).
Towards the end of the brand’s life, there were interesting vehicles like Prowler and the Neon, but they just weren’t enough to keep it profitable. Chrysler intended for Plymouth to have a resurgence with the PT Cruiser but the company ended up pulling the plug on the brand in 2001.
