Mutt Mongrel 125 (2016)
2016 Mutt Mongrel 125
CarHunch analysed 133 real MOT records for the 2016 Mutt Mongrel 125. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2016 Mutt Mongrel 125 has a first-time pass rate of just 60.8%, well below the UK average of 80%, which signals genuine reliability concerns for this model year. With 13.5% of vehicles having experienced a dangerous defect, buyers should factor in extra inspection costs and budget for repairs beyond routine maintenance.
These machines average just under 6,300 miles despite being eight years old, suggesting low-mileage vehicles that may have been stored or used sparingly—a mixed blessing that can hide wear in systems that don't get exercised. At 0.98 failures and 2.3 advisories per vehicle, the typical Mongrel 125 is developing issues faster than the average, so have a pre-purchase inspection performed by someone familiar with this specific model before committing.
What to check before buying a 2016 Mutt Mongrel 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.
