2007 Mazda 6 2.0L Petrol · FV07 DPX

This 2007 Mazda 6 carries a remarkably thin official defect history but presents an unusual and potentially concerning pattern of failed tests that returned no recorded advisories, suggesting retest submissions rather than genuine mechanical faults being identified. The most recent test on 16 March 2026 was a pass with no defects, which follows a failed test six days earlier with again no defects recorded, and a further failed test on 14 February 2026 also free of advisories. The same situation occurred at the 2025 test, where a pass and a fail were both logged on the same day in February with zero defects noted. While this clean advisory record superficially suggests excellent mechanical condition, the clustered pass-fail pairs raise questions about whether items were addressed between tests or whether pre-existing advisories were simply not re-recorded, meaning the actual mechanical condition may not be as transparent as the paperwork implies. A prospective buyer should treat the absence of advisories with appropriate scepticism given this testing rhythm. With 72,794 miles accumulated over approximately 19 years, this vehicle averages only around 3,831 miles annually, which is substantially below typical usage for a car of this vintage. This low-mileage profile mechanically implies reduced wear on major drivetrain components such as the engine, gearbox, and clutch, but it also raises the likelihood of corrosion through standing time, deterioration of rubber and polymer components like suspension bushes, coolant hoses, drive belts, and brake hydraulic seals, and potential issues from infrequent fluid cycling. The testing record shows annual attendance without multi-year lay-up gaps, indicating the car has remained in regular use and likely on the road, which mitigates some concerns about long-term storage degradation but does not eliminate them. Buyers should be particularly attentive to age-related polymer and rubber failures rather than wear-related issues, as these are less dependent on mileage than on calendar age. Given the complete absence of recorded component defects across all five tests, there are no specific flagged systems to target, but a thorough inspection should nonetheless focus on areas commonly affected on a Mazda 6 of this generation, particularly rear suspension bushes and trailing arm components, front subframe corrosion around the mounting points, and brake pipe condition along the underbody and rear axle where corrosion can develop unseen. On a test drive, listen carefully for clonks or knocking from the rear suspension over uneven surfaces, which would indicate worn bushes or failing damper mounts, and feel for any vagueness or knocking through the steering that could point to front suspension arm wear. Pay attention to brake pedal feel for excessive sponginess suggesting perished brake fluid or compromised flexible hoses, both of which are age-related rather than mileage-related concerns on a low-use vehicle. The powertrain should also be evaluated with the low-mileage context in mind, as the 2.0 or 2.3 litre petrol engines fitted to this generation Mazda 6 can suffer from oil leaks around the cam cover gasket and from timing chain tensioner wear if the vehicle has spent extended periods stationary. During inspection, check for oil residue around the cam cover, listen at startup for any initial rattle from the timing chain that may settle once oil pressure builds, and inspect the underside for any signs of weeping from the sump gasket or oil cooler pipes. Examine all coolant hoses for surface cracking or hardening, as these degrade with age regardless of mileage, and verify the condition of the radiator and cooling fan operation. Finally, given the unusual MOT pass-fail pattern with no defects recorded, consider requesting evidence of any rectification work undertaken between failed and passed tests, and factor in the need for an independent pre-purchase inspection to confirm the true mechanical state behind the unusually clean paperwork.
