The 2005-2010 BMW 523i Sedan, part of the E60 generation, is a mid-size luxury executive car known for its sharp handling and responsive steering. Enthusiasts and reviewers appreciate its blend of performance and advanced technology, such as the initial iDrive infotainment system and adaptive headlights.
