The 2003 Cadillac Seville, last of its fifth generation, is a luxury sedan that delivers strong performance and classic styling. Two trims, the luxury SLS and sporty STS, are available. Both trims come equipped with a 4.6-liter Northstar V8, but while the SLS offers 275 horsepower, the STS ups the output to 300. A slick 4-speed automatic transmission delivers power to the front wheels. Inside, a Bose sound system, leather upholstery, heated seats, and dual-zone climate control provide comfort. On the safety front, features include ABS brakes, traction control, and front and side airbags. However, there are no advanced driver-assist features like those found in contemporary models. Noteworthy for this year is the commemorative edition STS featuring a unique White Diamond exterior paint color and exclusive chrome wheels.
