Should I check the MOT history before buying a 2005 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 2005 BMW 630 passes its MOT at almost exactly the UK average of 79.3%, which is reassuring for a 19-year-old car—but the real concern is that 41.2% of these vehicles have shown dangerous defects at some point, well above typical thresholds. This high rate of serious faults suggests potential issues with critical safety systems that buyers should investigate carefully before purchase.

These cars are running at a reasonable 80,179 miles median, though they're racking up an average of 3.82 failures per test and a notable 20.3 advisories, indicating accumulated wear across multiple systems rather than isolated problems. If you're considering one, factor in that maintenance costs are likely to be substantial—get a pre-purchase inspection focused on suspension, braking components, and electrical systems, which tend to be the culprits on ageing BMWs.

The 2005 BMW 630 has a decent first-time pass rate (79.3%), 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 20.3 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 1,153 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.
