Allowing for age (not mileage), these Vauxhall models fail 16% more often than normal: brand MOT Risk Index 115.6 (95% CI 115.4–115.8; 100 = normal). Among Vauxhall models with at least 10,000 first tests, the Vauxhall Viva has the lowest index (83.5) and the Vauxhall Vivaro (van) the highest (151.9). On raw pass rates, the Vauxhall Grandland comes first instead, because the models' fleets differ in age.
