Summary Verdict

The 2000 BMW 323i (E46) is a capable and engaging sedan that, despite its age, can offer reliable service if well-maintained. Key areas to inspect and potentially address include the cooling system for leaks, VANOS system for performance issues, and suspension components like control arm bushings and ball joints for wear. Electrical gremlins, particularly with window regulators and ABS modules, are not uncommon. While the manual transmission is generally robust, the automatic can develop shifting issues. Routine maintenance is crucial, but beyond that, focusing on these specific potential failure points will contribute significantly to a positive ownership experience. Overall, it remains a desirable car for enthusiasts, but potential buyers should be aware of these common issues and budget accordingly for repairs.
