Should I check the MOT history before buying a 1991 BMW 5 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.

What corrosion should I look for when inspecting a 1991 BMW 5 Series?

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 1991 BMW 5 Series?

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.

Is the 1991 BMW 5 Series reliable?

Based on MOT data from 1,441 vehicles, the 1991 BMW 5 Series has a first-time MOT pass rate of 68.2%, indicating average reliability for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 1991 BMW 5 Series?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 1991 BMW 5 Series passes its MOT first time just 68.2% of the time—notably below the UK average of 80%—which tells you these cars demand careful inspection before purchase. With 13.3% having recorded dangerous defects, structural or brake problems aren't uncommon enough to ignore, though they're not endemic.

At nearly 146,600 miles average, these examples are well-used but not unusually so for a 33-year-old car; the real concern is that owners face an average of 1.45 failures per test, suggesting age-related wear is catching up fast. Budget for frequent remedial work and have any prospective purchase thoroughly inspected by a BMW-specialist mechanic before committing.

The 1991 BMW 5 Series has a below-average first-time pass rate (68.2% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Around 1 in 8 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 4.3 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 1,441 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.
