The 1999 BMW Z3's 72.5% first-time pass rate sits noticeably below the UK average of 80%, signalling that these cars are aging less gracefully than their peers. More concerning, over a third (34.5%) have experienced dangerous defects at some point, which is a serious red flag for any buyer considering this 25-year-old roadster.

The median mileage of 75,641 is reasonable for the age, but the real story lies in the failures themselves—averaging 5.16 per vehicle and 30.4 advisories tells you these Z3s need consistent, expensive attention to stay roadworthy. Before committing to one, budget for comprehensive pre-purchase inspection focusing on suspension, cooling, and electrical systems, as the advisory count suggests these are the chronic weak points.

The 1999 BMW Z3 has a below-average first-time pass rate (74.1% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 30.4 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 6,006 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.
