Quick summary
Total: 175 cars
The MG B from 1976 has a higher overall defect rate compared to the yearly average, with 151 defects per 100 vehicles, which is 48% worse than the average of 102 per 100. Notably, this model exhibits significantly more defects in several categories, especially in brakes and steering, where defect rates are 66% and 52% higher than the average, respectively. It also faces challenges with visibility and lights, showing more issues than typical models of the same age. Despite these concerns, the MG B performs better than average in terms of wheels, suspensions, and body structure, indicating some strengths in its design. Overall, while it has its positive aspects, the MG B’s higher defect rates in crucial areas suggest that it may require more frequent maintenance than its contemporaries.
