S370 JCW MOT History
Interpretation generated from the recorded test data above — not an official DVSA statement and not a substitute for an independent inspection.
5 MOT tests are recorded for this 1998 Mazda Mx-5 (S370 JCW) between April 2024 and September 2025.
The record contains 2 passes and 3 failures.
The most recent test on 29 September 2025 was a pass, although the earlier record includes 3 failures that buyers may want to investigate.
Across all tests, the most frequently flagged areas are: Windscreen (4 issues), Brakes (4 issues), Suspension (4 issues), Lighting (2 issues), Exhaust & Emissions (2 issues). Repeated mentions in one area can indicate an ongoing pattern worth checking in person.
In total 1 advisory notice is recorded. Advisories flag items that passed but may need attention before the next test; they are not evidence of how well the vehicle has been serviced.
Recorded failure items include: “Exhaust carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits (8.2.1.2 (a))”; “Nearside Front Suspension arm ball joint dust cover no longer prevents the ingress of dirt (5.3.4 (b) (ii))”; “Nearside Front Wheel bearing has excessive play (5.1.3 (a) (i))”.

Our Verdict
Proceed with extreme caution. While the MX-5 is a classic driver's car, this specific example shows significant structural corrosion and recurring mechanical issues that suggest a history of deferred maintenance.
If you are considering this car, your first priority must be a professional inspection of the chassis and sills. The MOT history from June 2025 explicitly flagged major corrosion on the nearside suspension mounting areas and the outer sill, which can be an expensive and difficult repair. Do not take a recent 'Pass' at face value without verifying that these structural repairs were carried out to a high standard and not just patched up.
Secondly, ask for a comprehensive service history. The car has a recurring pattern of exhaust-related failures (carbon monoxide and Lambda readings) dating back to 2021, suggesting potential issues with the fuel system, sensors, or engine health. Ensure the recent repairs to the wheel bearings, suspension ball joints, and braking system (which saw binding issues in late 2025) have been documented with receipts.
Running this 1.6L petrol MX-5 should be relatively affordable in terms of day-to-day use, with typical fuel economy and insurance groups for a car of this era. However, maintenance costs for this specific vehicle may be higher than average due to the age and high mileage.
You should budget for more frequent mechanical attention. The history of brake binding, suspension component wear, and exhaust issues suggests that 'preventative' maintenance might actually be 'reactive' maintenance on this car. Expect higher-than-average costs for structural upkeep and potential engine management repairs.
Start with the underside. Given the June 2025 failure for 'excessive corrosion significantly reducing structural strength' on the sills and chassis, you must check for any signs of recent welding or surface-level repairs that might hide deeper rot. Check the seat belt anchorages as well, as these have been flagged for corrosion in multiple previous MOT tests.
Next, inspect the braking and suspension systems. The most recent MOT history shows a history of binding brakes (both nearside and offside rear) and issues with wheel bearings and ball joint dust covers. Finally, check the exhaust system and engine idling; the car has repeatedly failed on carbon monoxide and Lambda levels, which could indicate an expensive fix for the catalytic converter or fuel system.
This 1998 Mazda MX-5 (S370JCW) in Red has covered 167,363 miles, which is quite high for its age. While it recently passed its MOT in September 2025, the recent history is concerning, featuring major failures for structural corrosion on the sills and chassis, alongside repeated exhaust emissions issues. The vehicle appears to be struggling with both its structural integrity and its engine's combustion efficiency.
While the MX-5 is generally regarded as a robust enthusiast car, they are notoriously susceptible to chassis corrosion if not treated with care.
