2005 BMW 630

CarHunch analysed 1,153 real MOT records for the 2005 BMW 630. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

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.

What to check before buying a 2005 BMW 630

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • ⚠️ 41.2% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
