Quick summary
Total: 455 cars
The 2005 MG ZR exhibits a lower overall defect rate of 277 per 100 vehicles compared to the yearly average of 376, making it 26% better than similar models from the same year. Notably, it is significantly less prone to defects in categories such as brakes and visibility, with 49% and 39% fewer issues, respectively. However, the model shows a concerning trend in steering defects, where it has a defect rate nearly double that of the average. Mileage-related trends indicate that while the defect rate increases with mileage, the MG ZR performs comparatively well up to 93,000 miles before the defect rate rises sharply.
