Quick summary
Total: 288 cars
The 2003 MG ZS has an overall defect rate of 332 per 100 vehicles, which is 12% lower than the average for cars of the same year, at 378 per 100. While tyre wear is not highlighted as a significant issue, the MG ZS performs exceptionally well in categories such as Steering and Visibility, showing notably fewer defects than average. However, it does have a higher incidence of defects related to Body and Structure, indicating a potential area for concern. Mileage-related trends suggest that defects increase with higher mileage, particularly in the 124,000+ mile range, which exceeds the average defect rate for that segment.
