Should I check the MOT history before buying a 2012 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 2012 BMW 6 Series passes its MOT first time at 85%, which is a solid 5 percentage points above the UK average—however, 42.8% of these cars have recorded a dangerous defect at some point, which is nearly double the typical rate and a genuine concern for any buyer. This suggests mechanical or safety issues lurk beneath the surface despite the respectable pass rate.

At 67,301 miles median mileage, these are fairly high-mileage examples for a twelve-year-old car, and they're averaging 1.84 failures per test, meaning most will need repairs before passing their next MOT. The high advisory count of 7.5 per vehicle points to wear across multiple systems—suspension, brakes, and trim are likely culprits—so budget for ongoing maintenance if you buy one. Before committing, ask the seller for full MOT history and get an independent pre-purchase inspection to uncover what that dangerous defect rate really means for this specific car.

The 2012 BMW 6 Series has a decent first-time pass rate (85%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 85% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 7.5 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 673 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
