2014 Aston Martin DB9 5.9L Petrol · OO07 CWC

The 2014 Aston Martin DB9 most recently passed its MOT on 16 December 2025 with no defects or advisories recorded, continuing an unbroken run of clean test results stretching back to its first entry on 17 November 2017. Across eight consecutive DVSA examinations, the vehicle has not produced a single advisory note, which is an exceptionally rare outcome for any car, let alone a twelve-year-old high-performance grand tourer. This pattern strongly suggests that the keeper has maintained the car to a high standard, addressing wear items proactively rather than allowing minor defects to be flagged at test time. For a prospective buyer, this clean trajectory is highly reassuring, although it should be viewed alongside other indicators of care such as service history, Aston Martin dealer or specialist invoices, and the condition of consumables visible during a physical inspection. Recorded mileage stands at 36,528 miles over approximately twelve years, equating to an annual average of around 3,044 miles, which is genuinely low for a car of this type and age. This level of usage places the DB9 firmly in the low-mileage bracket, and the relatively even spacing between MOT tests suggests the vehicle has been exercised at modest but consistent intervals rather than left dormant for extended periods. The mechanical implications of this pattern are mixed: lower mileage typically preserves drivetrain components, clutches, and interior trim, but it also increases the risk of time-related degradation in items that deteriorate with calendar age rather than use. Buyers should be alert to evidence of either regular gentle running or potential long periods of standing, both of which carry distinct considerations for a hand-built luxury sports car. Given the absence of any recorded advisories and the low annual mileage, physical inspection should focus on the issues most likely to affect a sparingly used performance vehicle of this vintage. Tyres warrant particular scrutiny, as the sidewalls may exhibit perishing or cracking from age even if the tread depth remains adequate, and any tyres fitted more than five or six years ago should be replaced regardless of wear. Brake discs and calipers are prone to corrosion from standing, with surface rust on the disc faces being normal but any pitting, scoring, or evidence of a binding caliper requiring further investigation. The 12V battery is another time-served component likely to be due for renewal, especially if the car has been stored for long stretches, and the charging system should be checked for parasitic drain. Coolant, brake fluid, and gearbox oil all degrade with calendar age and should be confirmed as recently serviced, with brake fluid particularly important due to its hygroscopic nature. On a test drive, particular attention should be paid to the behaviour of the suspension, as low-mileage cars can develop dried or perished bushes, especially at the front wishbones and rear subframe mounts, producing clonks or knocks over uneven surfaces. The V12 engine should be observed for smooth cold starting, even idle, and consistent power delivery, while the automatic transmission should shift cleanly without hesitation or flare. Listen for any exhaust leaks, particularly around the manifolds and rear silencers, and inspect the underbody, sills, and rear subframe for any signs of corrosion or fluid weeping, as standing moisture can accelerate oxidation in less-used vehicles. Finally, verify the operation of all electrical systems, including the infotainment, climate control, and convertible or coupe-specific mechanisms, as intermittent faults in these areas are common on cars of this age and complexity and may not be captured within the MOT test scope.
