Summary Verdict
The 2008 BMW 528i offers a compelling driving experience but requires attentive ownership due to potential reliability concerns, particularly with its electrical systems and certain engine components like the PCV system and cooling components. Transmission issues, especially with the automatic, can be costly. While the manual transmission is generally more robust, the automatic variants have documented vulnerabilities. The suspension and exterior/interior components are less prone to major issues. Prospective buyers should factor in potential repair costs for common problems such as oil leaks, electrical glitches, and transmission-related faults. Regular preventative maintenance and prompt attention to warning lights are key to maintaining this luxury sedan.
