The 1986 Rover Mini has an overall defect rate of 176 per 100 vehicles, which is significantly lower than the average for its year at 240 per 100, marking a 27% improvement. Notably, this model excels in several categories, particularly brakes, where it has a defect rate of 50%, compared to the average of 88%. It also performs better in steering, visibility, lights, and body structure. However, the Mini shows increased defect rates in the lowest mileage brackets, particularly between 0-31,000 miles and 31,000-62,000 miles, indicating potential issues that may arise early in its life. Overall, the Rover Mini demonstrates solid reliability compared to its contemporaries.
