The 2020 Isuzu Grafter N35.125 passes its MOT first time in 83.4% of cases, which sits comfortably above the UK average of 80% and suggests solid baseline reliability. With only 11.7% of vehicles ever having recorded a dangerous defect, this truck is reasonably safe from a structural or critical failure perspective.

The 2.8 average advisories per test suggest minor maintenance items crop up regularly—typical for working vehicles—so budget for routine attention to suspension, lights, and wear items rather than expecting trouble-free ownership.

What to check before buying a 2020 Isuzu Trucks Grafter N35.125

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.
