The 2011 BMW Z4 passes its MOT at 85.9%, which is a solid 5.9 percentage points above the UK average, suggesting these sports cars are being maintained reasonably well by their owners. However, nearly half of all Z4s in this cohort—46.1%—have recorded a dangerous defect at some point, which is a serious concern for any prospective buyer and warrants a thorough pre-purchase inspection.

At just under 47,000 miles on average, these Z4s are running relatively low mileage for their age, indicating they're often weekend or leisure vehicles rather than daily drivers. The average vehicle still picks up 2 failures and 9.4 advisories per test, pointing to wear in suspension, lighting, and trim components—typical of aging sports cars—so budget for ongoing maintenance when you buy one.

The 2011 BMW Z4 has a decent first-time pass rate (86%), 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 86% 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 9.4 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 2,122 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.
