The 2020 BMW 320i M Sport Auto passes its MOT slightly more often than the UK average, with an 83.2% first-time pass rate versus the national 80%, suggesting these cars are reasonably well-maintained overall—though the 12.1% that have experienced dangerous defects is worth noting as a buyer concern. Petrol versions (which make up the vast majority) perform marginally better at 81.8%, indicating consistent reliability across the fuel type.

These cars are running at sensible mileages for their age, with a median of just over 30,000 miles, and the low failure rate of 0.26 per vehicle suggests most don't require major repairs at MOT time. The 1.4 advisories per vehicle are fairly typical wear-and-tear items, so when buying one, focus your pre-purchase inspection on electrical systems and suspension components—the areas where BMWs commonly develop niggles—rather than expecting widespread mechanical problems.

The 2020 BMW 320i M Sport Auto passes its MOT first time more often than most UK vehicles (92.9% 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 92.9% 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 961 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.
