6. Plymouth Prowler
The hot rod culture is one of the key pieces of overall American automotive culture. However, no company ever dared to present a factory-built hot rod until 1997 when Plymouth presented the Prowler. It was a retro-futuristic roadster with a V6 engine and a unique look.
They imagined the Prowler as a follow-up to the Viper. Fortunately, the Prowler was a hit on the show circuit, and Chrysler understandably wanted to capitalize on that. Despite having some initial success, the car proved to be a failure and now ranks as one of the biggest sales flops. Customers expected V8 power instead of V6 power.
