Should I check the MOT history before buying a 2020 BMW X6 Xdrive30d M Sport Auto?

Moderate sample. 414 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2020 BMW X6 diesel is slightly more reliable than average, with an 84.7% first-time pass rate against the UK benchmark of 80%, and only 14.2% of vehicles have ever recorded a dangerous defect—a reassuringly low figure for a vehicle in this class. The 0.37 failures per vehicle suggests owners rarely face serious structural or safety issues once they've addressed any initial problems.

At 34,357 miles median for a four-year-old model, these cars are running well below the expected 40,000-mile average, indicating either careful ownership or low annual mileage, which bodes well for longevity. The 1.6 advisories per vehicle is moderate, typically pointing to wear items like brakes and suspension rather than mechanical faults, so budget for regular maintenance but don't expect expensive surprises—get a pre-purchase inspection focused on the diesel particulate filter and gearbox health before committing.

The 2020 BMW X6 Xdrive30d M Sport Auto passes its MOT first time more often than most UK vehicles (90.9% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

For context

✅ Good baseline reliability. A 90.9% 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 414 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.
