The 2003 Chevrolet Impala, a full-size sedan, marked the return of the iconic nameplate after a six-year hiatus. It was a significant departure from its predecessors, featuring a modern, aerodynamic design with a spacious and comfortable interior. The Impala was built on the GM W-body platform, sharing underpinnings with other popular models like the Buick LeSabre and Pontiac Grand Prix. Under the hood, it offered a choice of two engines: a 3.4L V6 producing 180 horsepower or a powerful 3.8L V6 generating 200 horsepower.
