Mercedes Benz V (2021)
2021 Mercedes Benz V
CarHunch analysed 120 real MOT records for the 2021 Mercedes Benz V. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Mercedes-Benz V is more reliable than average, with an 87.6% first-time pass rate that comfortably beats the UK average of 80%, though one in five vehicles have shown a dangerous defect at some point, which is worth factoring into your inspection. The diesel engines (which account for virtually all of these vehicles) perform consistently well at 87.8% pass rate.
At just over 30,000 miles median mileage for a three-year-old van, these are lightly used vehicles, so low mileage shouldn't be a red flag. The average of 0.47 failures and 1.5 advisories per vehicle suggests you're more likely to walk away with only minor wear items flagged than serious problems, but budget for a pre-purchase inspection that specifically checks the structural and safety areas where that 20% dangerous defect rate has shown up.
What to check before buying a 2021 Mercedes Benz V
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.
- ⚠️ 20% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
