Summary Verdict

The 2011 BMW 650Ci is a capable luxury vehicle, but potential buyers should be aware of common issues, particularly with the V8 engine’s valve stem seals and cooling system, as well as potential leaks and torque converter problems in the automatic transmission. Electrical gremlins, such as iDrive system glitches and window regulator failures, are also noted.
