Should I check the MOT history before buying a 1998 Mercedes Benz Ml?

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 Mercedes Benz Ml?

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.

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 Mercedes-Benz ML passes its MOT first time in just 69% of cases, well below the UK average of 80%, and nearly 3 in 10 examples have recorded a dangerous defect at some point—a significant concern for a used buyer. This is a reliability red flag: you're looking at a 26-year-old premium SUV with an above-average failure rate that demands serious pre-purchase inspection.

At around 103,000 miles median, these vehicles show typical wear for their age, but they're averaging 3.6 failures and 15.3 advisories per test, suggesting aging electrics, suspension, and emission systems are common culprits. Before committing to purchase, have an independent specialist conduct a full pre-sale check focusing on cooling system integrity and suspension wear—routine neglect on these cars turns into expensive surprises quickly.

The 1998 Mercedes Benz Ml has a below-average first-time pass rate (69.2% 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 15.3 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 731 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.
