Should I check the MOT history before buying a 1998 Mazda Demio?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 1998 Mazda Demio?

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.

How are tyres and brakes typically on a 1998 Mazda Demio?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Based on MOT data from 695 vehicles, the 1998 Mazda Demio has a first-time MOT pass rate of 71.9%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

The 1998 Mazda Demio struggles at MOT time, with a first-time pass rate of just 68.6%—nearly 12 percentage points below the UK average of 80%—and nearly one in five (19.1%) have recorded a dangerous defect, making this a reliability concern for buyers. The relatively modest mileage for a 26-year-old car (median 76,415 miles) suggests these vehicles may be stored or lightly used, yet they're still racking up an average of 3.13 failures per test, pointing to age-related decay rather than hard miles.

With an average of 13.6 advisories per vehicle, recurring minor issues like corrosion, brake wear, and lighting are dragging these cars down. If you're seriously considering one, budget for pre-purchase inspection and a safety check of brakes and suspension before committing, as the MOT history indicates structural and mechanical problems are common even on lower-mileage examples.

The 1998 Mazda Demio has a below-average first-time pass rate (71.9% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Around 1 in 8 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 13.6 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 695 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.
