2,089 MOT tests on the 2021 Mercedes-Benz Vito 114 Progressive + are in this dataset, and 82.0% of them passed. All cars of a similar age fail 8.6% of the time, so this is 9.4pp worse than the group it competes with. Failures cluster in lighting & signalling, visibility and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (9.4%) and visibility (7.8%) are close, so failures are spread across several systems rather than one weak point.

What to check before buying a 2021 Vito 114 Progressive +
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 9.4% of tests. Start there.
- Lighting & signalling (9.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (7.8% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Tyres (6.2% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
