The 2003 Mazda Demio falls slightly below the UK average at 76.4% first-time pass rate, and a concerning 26.3% of these cars have recorded a dangerous defect at some point—well above the typical threshold. This suggests reliability is middling for the age, with structural or safety issues appearing in roughly one in four examples.

These Demios have typically covered around 53,900 miles for their age, which is reasonable, but owners face an average of 4 failures and nearly 20 advisories per test cycle. Before buying, get a pre-purchase inspection focused on brake and suspension work, as the high advisory count indicates wear-related problems are common rather than freak occurrences.

The 2003 Mazda Demio has a decent first-time pass rate (76.4%), 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

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 19.5 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 612 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.
