The 2005 BMW 6 Series passes its first MOT attempt 82.7% of the time, marginally above the UK average of 80%, but the serious red flag here is that 35% of these cars have recorded a dangerous defect at some point—nearly double the typical rate. This suggests electrical, brake, or structural issues are endemic to the model, and any prospective buyer should factor in potentially expensive repairs.

These 6 Series have covered a typical 74,500 miles for their age, yet they're racking up an average of 2.92 failures and a concerning 14.1 advisories per test. The high advisory count points to wear in trim, suspension, and ancillary systems that, while not immediate failures, signal upcoming costs; before purchasing, get an independent specialist inspection focused on the cooling system, electrical harnesses, and suspension components, which are known weak points on this generation.
