Should I check the MOT history before buying a 1999 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.

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.

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 1999 BMW 520 passes its MOT just 68.6% of the time—well below the UK average of 80%—and nearly 30% of these cars have recorded a dangerous defect at some point, making it a genuine reliability risk for a buyer. This isn't a car that ages gracefully: at 120,000 miles median mileage, these are tired examples averaging 4.13 failures per test, suggesting fundamental wear rather than one-off problems.

The 16.5 average advisories per vehicle hint at the typical maintenance burden: suspension components, seals, and trim are all succumbing to age and the model's engineering realities. If you're serious about one of these, budget for a thorough pre-purchase inspection by a BMW specialist and be prepared to walk away if the service history is thin or the failure count is climbing.

The 1999 BMW 520 has a below-average first-time pass rate (68.7% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 16.5 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 2,883 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.
