Should I check the MOT history before buying a 2006 BMW 630?

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.

The 2006 BMW 630 matches the UK average first-time pass rate at exactly 80%, but nearly half of these cars—47.2%—have suffered a dangerous defect at some point, which is a significant concern for any prospective buyer. This suggests mechanical reliability broadly tracks the national baseline, but the frequency of serious safety issues elevates the risk profile considerably.

At 76,577 miles median, these vehicles show typical wear for their age, yet they're averaging 3.57 failures and 19.5 advisories per test cycle, indicating ongoing maintenance demands. Before committing to one, have an independent pre-purchase inspection focus on braking, suspension, and electrical systems—areas where BMWs of this era tend to accumulate costly repairs.

The 2006 BMW 630 has a decent first-time pass rate (80.1%), 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 19.5 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 1,460 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.
