Should I check the MOT history before buying a 2020 BMW 8 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.

Moderate sample. 354 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2020 BMW 8 Series posts a strong 90.2% first-time pass rate, well ahead of the UK average of 80%, but one in four examples (25.4%) have suffered a dangerous defect during their MOT history—a genuine concern for a premium buyer. Petrol and diesel variants perform almost identically at 90.2% and 90.4% pass rates respectively, so fuel choice won't be a reliability differentiator here.

At 33,564 miles median mileage, these cars are running relatively lightly for their age, which explains the low average of 0.44 failures per vehicle. The 1.6 advisories per car suggest minor wear items crop up routinely, but the real red flag is that one-in-four dangerous defect rate—get a thorough pre-purchase inspection and full service history before committing to any example, regardless of its apparent MOT track record.

The 2020 BMW 8 Series has a decent first-time pass rate (90.2%), 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 90.2% 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 1.6 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 354 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.
