The 2015 Mercedes-Benz Viano's 81.3% first-time pass rate slightly edges the UK average, but the real concern here is that 41.9% of these vehicles have recorded dangerous defects—nearly double the typical threshold—suggesting structural or safety issues are common across the fleet. This is a material risk for any prospective buyer and warrants a thorough pre-purchase inspection.

At around 86,000 miles on average, these eight-year-old vans are showing typical wear for their age, yet they're still generating 2.31 failures and 12.4 advisories per test cycle, indicating maintenance demands are substantial.
