Reading the Mercedes-Benz A-Class’s numbers
The Mercedes-Benz A-Class passes its MOT first time more often than the average UK car — 75.9% against 71.4% nationally, across 247,288 real tests. Pass rates reflect the age and upkeep of the cars tested as well as the design — an older fleet drags a model’s rate down.
