Should I check the MOT history before buying a 2015 BMW 518?

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.

The 2015 BMW 518 passes its MOT first time in 88.2% of cases, well above the UK average of 80%, which is a genuine strength—but 36% of these cars have recorded a dangerous defect at some point, a notably high figure that warrants a pre-purchase inspection by a BMW-specialist mechanic. This is a car that's generally well-maintained by its owners, yet carries real risk if you don't know its history.

At 88,000 miles median, these are genuinely well-used saloons, and the 1.13 average failures per MOT suggest owners are staying on top of major issues rather than letting them accumulate. The high advisory count of 7.7 per test reflects typical BMW wear-and-tear—electrics, suspension bushings, and sensor faults are par for the course—so budget for frequent small repairs and always get a full service history before committing.

The 2015 BMW 518 has a decent first-time pass rate (88.2%), 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 88.2% 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 7.7 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 680 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.
