Should I check the MOT history before buying a 2021 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 2021 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.

How are tyres and brakes typically on a 2021 BMW 7 Series?

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.

Is the 2021 BMW 7 Series reliable?

Based on MOT data from 381 vehicles, the 2021 BMW 7 Series has a first-time MOT pass rate of 93.3%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 BMW 7 Series?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

Moderate sample. 381 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2021 BMW 7 Series is significantly more reliable than average, with a 93.3% first-time MOT pass rate well above the UK average of 80%, and only 12.6% of vehicles ever presenting a dangerous defect—a reassuring figure for a luxury saloon. The hybrid electric version (which accounts for 312 of the 381 cars tested) performs marginally better at 93.7%, suggesting the electrified powertrain is holding up well.

At just under 38,000 miles median, these cars are still relatively young and lightly used, which partly explains the strong pass rates, though the low average of 0.27 failures per vehicle shows BMW's engineering is delivering on durability. Buyers should still budget for the 1.0 advisory per car on average—typical wear items for a premium saloon—and have a pre-purchase inspection focus on suspension and electrical systems, where luxury cars often accumulate costly issues.

The 2021 BMW 7 Series passes its MOT first time more often than most UK vehicles (93.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 8 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 93.3% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔍 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 381 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.
