Should I check the MOT history before buying a 2006 BMW 120?

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.

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 2006 BMW 120 is right at the UK average for first-time pass rates at 79.1%, but a serious concern emerges in the detail: nearly half of these cars (45.2%) have recorded a dangerous defect at some point, well above what you'd expect. The diesel versions, which make up 87% of the cohort, perform slightly worse than petrol at 78.7% versus 81.9% pass rates—a meaningful gap for a vehicle now 18 years old.

These cars are running at sensible mileage for their age, with a median of 94,376 miles, yet they're averaging nearly four failures and 26 advisories per test, suggesting wear is catching up fast. Before buying one, get a pre-purchase inspection focused on the suspension, brakes, and cooling system, since high-mileage BMWs of this generation develop predictable issues in those areas.

The 2006 BMW 120 has a decent first-time pass rate (79.1%), 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

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 26.5 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 4,983 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.
