The 1990 Mercedes-Benz C falls short of the UK average with a 73.1% first-time pass rate, and nearly a quarter of these cars have experienced dangerous defects during their MOT history—a genuine concern for a 34-year-old vehicle. At 135,311 miles median mileage, these examples have covered typical distance for their age, yet they're averaging 2.57 failures per MOT, suggesting age-related wear is catching up.
