It can be, but only if the individual car backs it up. For the 2017–2020 BMW 6-Series, treat model-level patterns as viewing priorities and let condition, history and inspection evidence decide.
The problem cards above list the model-level checks for this guide. Read them as priorities for inspection and paperwork review, not proof that every example will have those faults.
Look for evidence, not just assurances: MOT advisories, service history, repair invoices, warning lights, fluid leaks, tyre and brake condition, and how the car behaves on a proper test drive. And of course, look at your personalised Should I Buy This Car? report, outlining a full list of common issues in detail, a personalised road test, a plain-English explanation and a MotorIQ score.
The guide above gives you the model-level pattern. A personalised MotorIQ report checks the registration-specific record and turns it into an ownership view before you commit.
