Should I check the MOT history before buying a 2016 Mutt Mongrel 125?

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 2016 Mutt Mongrel 125?

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.

How are tyres and brakes typically on a 2016 Mutt Mongrel 125?

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.

Based on MOT data from 133 vehicles, the 2016 Mutt Mongrel 125 has a first-time MOT pass rate of 74.8%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2016 Mutt Mongrel 125?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

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.
