The Mercedes - has an overall MOT pass rate of 78.2% across 487 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
The most common problems on the Mercedes - are suspension arm ball joint dust cover excessively deteriorated so that it no longer prevents the ingress of dirt front arm dust cover (1 recorded failures), mechanical brake component has restricted free movement both (1), and anti-roll bar synthetic bush deteriorated resulting in excessive movement both drop links (1). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
A typical Mercedes - owner drives around 13,580 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.
