2007 Mazda 6 2.0L Petrol · KJ07 AAE

The most recent MOT, carried out on 31 October 2025, was a pass but carried several advisories covering front and rear brake discs, rear inner suspension mounting corrosion and minor tyre condition notes. Over the past two years the pattern has been mixed: a failure in October 2025 was followed by a pass with the same brake‑disc advisories, a pass in 2024 with a broader set of corrosion and tyre warnings, a clean pass in 2023 and a failure that year for a front position lamp. The trend suggests a generally stable maintenance regime – the vehicle is being kept road‑legal – but recurring wear on the brake discs and progressive corrosion on suspension and sub‑frame areas indicate that some items have not been addressed proactively. At 84 087 miles recorded for a 2007 model the average annual mileage works out at roughly 4 400 mi per year, well below the typical 8‑10 000 mi UK average. Such low utilisation often points to long periods of inactivity or very gentle use, which can be a double‑edged sword. While the engine and drivetrain have been spared high‑stress mileage, components that rely on regular movement – rubber seals, bushings, tyres and battery plates – are prone to ageing, cracking and corrosion when left idle for extended spells. The modest mileage also means that wear items such as brake discs may not have been replaced despite reaching the end of their service life, as reflected in the repeated advisories. When you inspect the car, give the brake system the greatest attention. Verify the actual disc thickness with a micrometer; the legal minimum is 1.6 mm but replacement is advisable well before that, especially with the pitting noted on all four discs. Look for uneven pad wear, scoring on the rotors and any pulsation or shudder when applying the brakes at moderate speed – symptoms of thinning or warped discs. Check the brake fluid level and condition; a dark, moisture‑laden fluid should be flushed, and inspect the off‑side front brake pipe for rust or grease buildup that could indicate a future leak. Examine the rear inner suspension mounting area and both rear suspension arms for rust, cracked paint or excessive play in the bushings – any looseness will manifest as clunking over bumps or a vague wandering feel at higher speeds. Finally, assess the tyres for age and condition: the near‑side front tyre shows early cracking, and the off‑side front tyre is close to the legal tread limit, so both may need replacement regardless of remaining tread depth. Look for sidewall cracks, dry rot or hardening, especially if the tyres are older than six years. Inspect the sub‑frame and rear chassis for surface rust that could be progressing beneath paint, and ensure the front position lamp is functional. Given the vehicle’s age and likely periods of standing, have the 12 V battery load‑tested, confirm that the engine oil, coolant and transmission fluids have been changed within the recommended intervals, and request any service stamps that verify regular oil and filter changes. Addressing these items now will give a clearer picture of the car’s true roadworthiness and help avoid unexpected failures after purchase.
