Should I check the MOT history before buying a 2017 BMW 6 Series?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2017 BMW 6 Series punches well above the UK average with a 89.9% first-time pass rate against the national 80%, suggesting these are generally well-maintained cars—though one in four have encountered a dangerous defect at some point, which is a meaningful buyer concern. The diesel-dominated fleet (215 of 263 cars) passes at 89.7%, indicating the engine platform is holding up reliably.

At 46,667 miles median, these 6 Series are running relatively light for their age, and the 0.76 average failures per vehicle signals they don't demand major repairs on test day—but the 4.3 advisories per car point to accumulating wear on electrics, suspension, and trim, which is typical of premium cars hitting seven years old. Before buying, inspect the service history carefully and budget for non-urgent advisory work, as these cars reward preventive maintenance over reactive repairs.
