The 2003-2010 BMW 520i Sedan, part of the E60 generation, is a premium executive car known for its controversial "Bangle Butt" styling and advanced technology for its time. Enthusiasts and reviewers often consider the 520i adequate for daily use, noting that while not a high-performance variant, it offers a refined ride. It is sometimes infamous for complex electronics and potential maintenance issues as the cars age, though it avoids the severe timing chain problems associated with later F10 520i models. In today's context, the 520i is well-suited for buyers seeking an affordable, comfortable, and stylish used luxury sedan for commuting or family transport, provided maintenance history is solid.
Maintenance for the 2003-2010 BMW 520i Sedan can be high. Common reliability concerns include timing chain problems, turbocharger failure, high-pressure fuel pump (HPFP) issues, and cooling system failures, leading to potentially costly repairs like alternator replacement ($1,265–$1,504).
