This Mercedes V-Class diesel is slightly more reliable than the UK average, with an 82.8% first-time MOT pass rate against the 80% benchmark, though the 20.6% of vehicles that have recorded a dangerous defect is a noteworthy concern for a buyer—worth investigating the specific nature of those failures. At 33,200 miles median for a 2021 model, these examples are carrying typical mileage for their age, and the 0.44 average failures per test suggests most issues caught are minor, though the 2.1 advisories per vehicle indicate some attention to maintenance is expected. Check the service history carefully and budget for brake and suspension work, which tend to accumulate advisories on larger vehicles like this; also ask the seller directly about any dangerous defects flagged in their MOT records.
