Beyond its aesthetically pleasing exterior, the Seville offered a spacious and comfortable interior, featuring premium materials like leather upholstery and wood trim. The Seville's emphasis on luxury extended to its standard features, including an eight-way power driver's seat, dual-zone climate control, and a premium Bose sound system. The Seville also offered a range of optional extras, such as a sunroof, navigation system, and a powerful Northstar V8 engine.
