2007 Mazda 3 1.6L Petrol · KJ07 TNW

The Mazda 3 presents a stable roadworthiness record in its most recent MOT cycles, with the October 2025 tests—both passed and failed—showing no defects at 104,500 miles. The absence of advisories or failures in the past two years suggests the vehicle has been maintained to a high standard, at least in terms of meeting DVSA minimum requirements. The duplicate test entries on the same date imply a minor administrative anomaly rather than a mechanical issue, and the clean pass rate since 2023 indicates no recurring faults have escalated. For a vehicle of this age and mileage, this consistency is unusual; most 19-year-old cars with similar low annual mileage would typically show signs of wear in brakes, suspension, or emissions systems. The mileage accumulation of roughly 5,500 miles per year is exceptionally low for a car of this age, suggesting either infrequent use or prolonged periods of inactivity. The gap between the 2023 and 2024 tests (98,665 to 101,432 miles) covers just 2,767 miles over 12 months, reinforcing the impression of light usage. Such low mileage reduces wear on consumables like tyres and brake pads, but it also raises questions about fluid health—oils, coolants, and brake fluid degrade over time regardless of mileage. The lack of recorded defects in any test further implies either meticulous maintenance or, less likely, a vehicle that has been stored rather than actively driven. Given the clean MOT history, a buyer should still conduct a thorough pre-purchase inspection, focusing on components that typically degrade even with low mileage. Particular attention should be paid to the suspension—check for worn bushes, degraded coil springs, or uneven tyre wear, which could indicate alignment issues. The brakes, while not flagged in the MOT, should be tested for binding or uneven pad wear, as low-mileage cars can still suffer from seized calipers or corroded discs if fluids have been neglected. Structural integrity is another key area; inspect for corrosion in wheel arches, sills, and underbody panels, especially given the vehicle’s age. Finally, verify all fluids—engine oil, brake fluid, coolant, and transmission fluid—are fresh and at correct levels, as stagnation can lead to hidden failures. While the MOT record is reassuring, the low annual mileage and lack of advisories create an unusual profile that warrants closer scrutiny. A buyer should treat this as a potential red flag for deferred maintenance rather than a flawless history. Prioritise a professional inspection to confirm no underlying issues have been overlooked.
