2002 Mazda MX-5 1.6L Petrol · HV02 BXD

The vehicle is currently roadworthy but the maintenance history indicates a worsening trend regarding structural and emissions integrity. While the most recent test in April 2025 at 158,085 miles passed, it followed a failure just one week prior due to high carbon monoxide emissions and suspension corrosion. The persistence of corrosion warnings across multiple years suggests that the underlying metalwork is being managed rather than fully preventatively repaired. Although the car passed its latest inspection two months ago, the recurring nature of these faults indicates that the vehicle is reaching a stage where component degradation is becoming frequent. At 158,085 miles over 24 years, the Mazda MX-5 has covered a consistent average of approximately 6,600 miles per year. The data shows a significant gap in mileage between October 2022 and November 2023, where only 2,366 miles were recorded in over fourteen months. This lower-frequency usage often correlates with the accelerated corrosion noted in the records, as stationary vehicles are more susceptible to moisture-related rust. The rapid accumulation of 1,022 miles between November 2023 and April 2025 suggests a return to more regular use, which has placed fresh stress on the aging emissions and suspension systems. A buyer must prioritize a thorough physical inspection of the subframes and integral body panels, as the 2022 record already flagged corrosion on the front and rear subframes as well as the seal panels. The 2025 failure for corroded suspension components confirms that the structural rust issue is active. Specific attention should also be paid to the exhaust system; the history of high lambda readings and excessive carbon monoxide in 2023 and 2025 suggests potential catalytic converter or fueling issues. Check the offside brake pipe and ball joint dust covers mentioned in 2022 to ensure previous defects were properly rectified rather than merely masked.
