Should I check the MOT history before buying a 2020 BMW 320?

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 2020 BMW 320?

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 2020 BMW 320?

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 2020 BMW 320 reliable?

Based on MOT data from 3,948 vehicles, the 2020 BMW 320 has a first-time MOT pass rate of 90.5%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

The 2020 BMW 320 is a genuinely reliable performer with a 90.5% first-time pass rate—well ahead of the UK average of 80%—though nearly 1 in 5 examples have picked up a dangerous defect at some point, which is worth factoring into your inspection checklist. At a median mileage of 31,782 miles for a 2020, these cars are running lighter than you'd expect, suggesting good maintenance across the cohort overall. The average car carries just 0.42 failures but 2.1 advisories, meaning most problems caught are minor wear items rather than showstoppers. Before committing, get a pre-purchase inspection focused on the electrical and suspension systems—BMW's weak spots—since advisories cluster around those areas.

The 2020 BMW 320 passes its MOT first time at roughly the UK average rate (90.5%) — solid but worth checking this vehicle's history carefully.

⚠️ 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 90.5% 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 2.1 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 3,948 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.
