Should I check the MOT history before buying a 2005 BMW 7 Series?

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 2005 BMW 7 Series?

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.

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 2005 BMW 7 Series diesel achieves an 82.1% first-time pass rate, marginally above the UK average of 80%, which suggests broadly solid reliability—but the concerning figure here is that 22.2% of these cars have recorded a dangerous defect at some point, well above the typical threshold and a genuine buyer concern. This is a luxury car that demands close inspection before purchase.

These 7 Series examples have covered around 95,600 miles on average, which is reasonable for their age, yet they're generating 2.5 failures and nearly 12 advisories per test, pointing to the expensive nature of keeping an aging BMW in good order. Factor in the high dangerous defect rate and demand a full service history and recent specialist inspection before committing to one.
