Man Unknown (2018)
2018 Man Unknown
CarHunch analysed 4,113 real MOT records for the 2018 Man Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2018 MAN is a commercial vehicle, and the 8.1% first-time pass rate reflects the far stricter MOT standards applied to HGVs and large goods vehicles compared to cars—not a sign of poor quality. Diesel dominance (99% of the cohort) and a 7.0% pass rate for those units is normal for this vehicle class, and dangerous defects are rare at just 1.7%.
At 87,000 miles median, these are working vehicles with typical commercial mileage for their age, and the low average of 0.08 failures and 0.3 advisories per test shows they're generally well-maintained when they do pass. If you're buying one, treat the pass rate as irrelevant to reliability—instead, focus on service history, brake condition, and whether it's been regularly inspected by a workshop familiar with commercial vehicles.
What to check before buying a 2018 Man Unknown
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
