The Mash Fifty has an overall MOT pass rate of 77.0% across 482 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
A typical Mash Fifty owner drives around 998 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
