The 2003 Cadillac Seville STS is a luxury sedan that embodies the epitome of American automotive craftsmanship and elegance. This model represents the final iteration of the fourth generation Seville, a lineage that had been synonymous with Cadillac's commitment to providing opulent driving experiences since 1976. The STS, an abbreviation for "Sport Touring Sedan," emphasized a more performance-oriented character compared to its standard Seville sibling. This was evident in its powertrain, featuring a robust 4.6-liter Northstar V8 engine capable of generating 300 horsepower and 325 lb-ft of torque. Coupled with a four-speed automatic transmission, the STS delivered a spirited driving experience, seamlessly blending power and comfort. Beyond its performance credentials, the Seville STS boasted an array of luxury amenities, including premium leather upholstery, heated and cooled seats, a Bose sound system, and a navigation system, offering a refined and comfortable cabin experience.

The 2003 Cadillac Seville STS was built on GM's Sigma platform, which underpinned a range of General Motors' full-size and luxury vehicles. This platform provided the STS with a well-balanced and composed ride, thanks to its independent suspension setup and advanced electronic stability control system. Safety was also a priority, with features like dual front airbags, side airbags, and traction control ensuring the occupants' well-being. While the Seville STS was praised for its performance, luxury, and comfort, it was ultimately discontinued in 2004, making way for the new Cadillac DTS. The Seville STS left its mark as a memorable and capable luxury sedan that embodied the spirit of American automotive excellence.
