Should I check the MOT history before buying a 2018 BMW 318?

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 2018 BMW 318?

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 2018 BMW 318?

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 2018 BMW 318 passes its MOT first time in almost 9 out of 10 cases—nearly 10 percentage points above the UK average of 80%—but a quarter of these cars have recorded dangerous defects at some point, which is a legitimate concern for buyers. Both petrol and diesel versions perform identically at around 90% pass rate, so fuel choice won't affect your reliability expectations.

At 41,289 miles median (48,033 average), these are still relatively low-mileage cars for their age, yet they're already averaging 5.2 advisories each, suggesting some wear items are beginning to flag. When failures do occur, they're relatively light at 0.68 per vehicle, but the high advisory count means budget for preventative maintenance—have any prospective purchase checked by an independent BMW specialist before you commit.

The 2018 BMW 318 has a decent first-time pass rate (89.8%), 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 89.8% 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 5.2 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 2,857 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.

Almost all 2018 BMW 318s are still on the road.

Strong survival — 2,691 vehicles still getting MOTs in 2025, 97% of the peak.

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2020–2025.
* The 2020 dip reflects the government's COVID-19 MOT exemption, which allowed certificates to be extended by six months — fewer tests were conducted that year.
