Should I check the MOT history before buying a 2009 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.

What corrosion should I look for when inspecting a 2009 BMW 120?

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 2009 BMW 120?

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 2009 BMW 120 passes MOT marginally above the UK average at 80.9% first time, but here's the serious concern: nearly half of all vehicles in this cohort have recorded a dangerous defect at some point, which is well above typical. Petrol models fare slightly better than diesels (82.3% vs 80.5% pass rate), but both variants carry this elevated safety risk.

At 81,121 miles median, these cars have covered typical distance for their age, yet they're accumulating substantial maintenance bills—averaging 3.15 failures and 19.4 advisories per test. Before buying one, get a full pre-purchase inspection focusing on suspension, braking, and steering components, as the dangerous defect rate suggests systemic issues beyond routine wear.

The 2009 BMW 120 has a decent first-time pass rate (80.9%), 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 19.4 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 4,556 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.
