Should I check the MOT history before buying a 2022 BMW 420i M Sport Auto?

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 2022 BMW 420i M Sport Auto?

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 2022 BMW 420i M Sport Auto?

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 2022 BMW 420i M Sport Auto reliable?

Based on MOT data from 2,915 vehicles, the 2022 BMW 420i M Sport Auto has a first-time MOT pass rate of 93.7%, 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 2022 BMW 420i M Sport Auto?

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.

The 2022 BMW 420i M Sport Auto is a reliable performer, passing its MOT on first attempt 90% of the time—a full 10 percentage points above the UK average—with only 6.1% of vehicles ever flagged for a dangerous defect, well below typical concern thresholds. At a median of 22,795 miles for a two-year-old car, these are genuinely low-mileage examples, which partly explains the strong results; the average failure rate of just 0.13 per vehicle confirms this is a mechanically sound generation. With 0.5 advisories per car on average, minor wear items are beginning to surface, but nothing alarming for the age and use. Before committing, have a BMW-specialist pre-purchase inspection done—these cars are expensive to fix out of warranty, so you want to catch any electrical or suspension niggles early.

The 2022 BMW 420i M Sport Auto passes its MOT first time more often than most UK vehicles (93.7% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 20 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 93.7% 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 2,915 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.
