Should I check the MOT history before buying a 2014 BMW 520?

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.

What corrosion should I look for when inspecting a 2014 BMW 520?

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.

How are tyres and brakes typically on a 2014 BMW 520?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2014 BMW 520 passes MOT first time at 87.2%, comfortably beating the UK average of 80%, but here's the catch: 37.3% of these vehicles have recorded a dangerous defect at some point, which is significantly higher than typical and a serious red flag for any buyer. Petrol and diesel variants perform similarly (89% and 87.2% respectively), so fuel choice won't change your reliability outlook.

These cars average 82,176 miles on the odometer, which is reasonable for a decade-old executive saloon, but the real concern emerges in the failure pattern: owners face an average of 1.34 failures per test and 8.6 advisories, suggesting routine maintenance issues aren't being caught early. Before committing to one, get a full BMW specialist pre-purchase inspection focusing on cooling system, suspension, and electrical components—the advisory count indicates these are the weak spots that could spiral into expensive repairs.

The 2014 BMW 520 has a decent first-time pass rate (87.3%), 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 87.3% 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 8.6 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 13,916 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.

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2017–2025.
* The 2020 dip reflects the government's COVID-19 MOT exemption, which allowed certificates to be extended by six months — fewer tests were conducted that year.
