Should I check the MOT history before buying a 1998 BMW 523?

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 1998 BMW 523 passes its MOT first time in only 69.6% of cases, significantly below the UK average of 80%, which signals genuine reliability concerns for a car of this age. More worryingly, nearly 3 in 10 of these vehicles (29.1%) have recorded dangerous defects during testing — a high figure that suggests buyers need to inspect any potential purchase very carefully and budget for repairs.

At around 121,000 miles on average, these cars have covered typical mileage for their 26 years, but they're failing badly because they're genuinely old and complex; the average owner faces 3.72 failures and 14.6 advisories per test, reflecting the cumulative wear on aged German engineering. Before committing to one, get a pre-purchase inspection focused on the suspension, cooling system, and brakes — the most common failure areas for BMWs of this generation.

The 1998 BMW 523 has a below-average first-time pass rate (69.6% 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 14.6 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 5,238 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.
