Should I check the MOT history before buying a 1998 Mazda 121?

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.

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.

The 1998 Mazda 121 has a first-time MOT pass rate of just 64.1%, well below the UK average of 80%, which signals reliability concerns for a car now 26 years old. More worryingly, 30.9% of these vehicles have recorded at least one dangerous defect during their MOT history—nearly a third—making this a genuine safety consideration for potential buyers.

These cars are averaging around 57,800 miles, which is relatively low for their age and suggests many have been lightly used; however, the real issue is that even at modest mileage, they're averaging 3.91 failures and 16.3 advisories per vehicle, indicating widespread wear and corrosion issues typical of aging Japanese city cars. Before buying one, have a pre-purchase inspection focus specifically on brakes, suspension, and bodywork rot, as the data suggests these are common failure points.

The 1998 Mazda 121 has a below-average first-time pass rate (64.1% 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 16.3 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 771 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.
