2004 Mazda MX5 Euphonic 1.8L Petrol · SL04 FLD

The 2004 Mazda MX-5 presents a mixed roadworthiness profile when examining its seven-year MOT history up to the most recent test on 2026-08-17, which returned a clean result with no recorded defects. While the majority of tests over the past six years have been successful, two instances of failure—on 2023-04-28 and again on 2026-07-24—indicate intermittent mechanical problems that were subsequently resolved before the latest passing examination. This pattern suggests the vehicle has been generally reliable but experienced periods of unreliability that have now cleared, leaving the current condition as one of stability following a brief spell of concern. With a recorded odometer reading of 69,524 miles on a 2004 model, the vehicle accumulates approximately 3,160 miles annually, a figure considerably lower than typical for its age and indicating either very light usage or extended periods of storage between drives. The testing interval between the 2026-07-24 failure and the 2026-08-17 pass spans just three days, while the gap to the prior pass in 2025-04-29 was nearly eight months, and the longest interval occurs between the 2022-04-19 pass and the 2023-04-28 failure at roughly five months. Such irregular spacing combined with the two prior failures points to underlying issues that required attention before each subsequent successful examination, though the lack of new defects in the August 2026 test provides reassurance that the vehicle is presently roadworthy. Given the low mileage profile, the suspension system is unlikely to exhibit significant wear on bushings or control arms, yet the two recorded failures warrant particular scrutiny of the shock absorbers and leaf springs for signs of premature degradation or damage that may not be immediately apparent. A thorough visual and tactile inspection of the rear subframe is recommended, as age-related corrosion can compromise chassis integrity even with modest mileage, particularly around bolt holes and weld seams. Additionally, the braking system should be examined for any persistent noises or soft spots during pedal travel, as the 2026-07-24 failure period coincided with a change in driving conditions that may have exposed existing weaknesses. The most critical areas to verify on a test drive are the front and rear axle steering components for play or binding, the brake disc and caliper mounting points for secure fastening and even pad contact, and the oil pan gasket area for any residual leakage that could indicate internal engine stress. Because the vehicle showed failures in April 2023 and July 2026, paying close attention to how the car responds through moderate acceleration and deceleration events will help determine whether the previously identified issues have fully resolved or require further investigation. If any of these systems remain questionable, requesting additional diagnostic checks before committing to purchase would ensure the low-mileage history does not mask hidden mechanical deterioration.
