Should I check the MOT history before buying a 2015 BMW 730?

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 2015 BMW 730?

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 2015 BMW 730 diesel passes its first MOT at 87.4%, meaningfully better than the UK average of 80%, which is a solid endorsement of its engineering durability. However, the dangerous defect rate sits at 34%—well above the typical threshold—so buyers should factor in potential costs for serious issues like brake or suspension failures.

These cars are running around 63,000 miles at test time, which is reasonable for their age and suggests typical usage patterns. The average of 1.07 failures per vehicle is low, but advisories average 5.5, indicating that while major problems are rare, maintenance items and wear items do accumulate—plan for regular servicing and have a pre-purchase inspection focus on suspension, brakes, and electrical systems before committing.

The 2015 BMW 730 has a decent first-time pass rate (88.6%), 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

✅ Good baseline reliability. A 88.6% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 5.5 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 670 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.
