The Mercedes-benz M8 has an overall MOT pass rate of 82.8% across 2,280 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
A typical Mercedes-benz M8 owner drives around 28,893 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.
In terms of longevity, most Mercedes-benz M8 models stay on UK roads for around 10 years. If you're buying one that's already well within that window, the data suggests it has plenty of life left provided it's been maintained.
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.
