The 2012 Mercedes-Benz Viano passes its MOT at 81.4%, marginally above the UK average of 80%, but a serious concern emerges in the safety data: 38.5% of these vans have recorded dangerous defects at some point, well above the threshold that should worry a potential buyer. This high rate of critical issues makes thorough pre-purchase inspection non-negotiable.
At nearly 102,000 miles on average, these vans have covered typical mileage for their age, yet they're racking up an average of 2.91 failures and 15.3 advisories per test—suggesting wear and maintenance demands accumulate steadily. Before committing to one, have a Mercedes specialist conduct a full diagnostic focusing on brake systems and suspension components, where dangerous defects are most commonly recorded on this model.
The 2012 Mercedes Benz Viano has a decent first-time pass rate (81.4%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.
These stats describe 763 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
