2017 Mazda 6 2.0L Petrol · BC66 USP

The 2017 Mazda 6 presents a stable and generally improving mechanical trend, culminating in a clean pass on 31 January 2026 at 25,424 miles. The most recent test recorded only two minor advisories for slightly defective headlamp lenses, which are cosmetic rather than structural. A year prior, on 1 February 2025 at 23,726 miles, the tester flagged front and rear brake pads wearing thin alongside worn and pitted rear discs. These items appear to have been addressed before the January 2026 test, as no brake-related defects reappeared. The record shows no recurring suspension, steering, or structural corrosion failures, suggesting the car has been maintained to a reasonable standard without persistent mechanical deterioration. The mileage profile is notably low for a nine-year-old vehicle. Between the January 2023 test at 20,089 miles and the January 2026 test at 25,424 miles, the car covered just 5,335 miles over three years, averaging roughly 1,778 miles annually. This pattern indicates either very light use or prolonged periods of inactivity. Low mileage can preserve certain components, yet extended sitting risks dried suspension bushes, seized brake calipers, and flat-spotted tyres. The MOT record lacks intermediate tests between 2023 and 2025, so there is a gap in documented condition during that period. Buyers should inspect the braking system closely despite the recent pass. The February 2025 advisories for worn pads and pitted rear discs point to a history of deferred brake maintenance. Check whether the discs have been replaced or merely skimmed, and examine the calipers for signs of binding. The headlamp lens defects flagged in January 2026 may seem minor, but degraded polycarbonate can scatter light and reduce night-time visibility. Inspect the lenses for haze or cracks. Given the low mileage and potential for long stationary spells, a thorough underbody inspection is advisable. Look for surface corrosion on subframes, suspension arms, and brake lines, as well as perished rubber bushes and tyre sidewalls. A test drive should focus on brake feel, pulling under braking, and any suspension knocks that might indicate dried or worn components.
