2015 Aston Martin DB9 5.9L Petrol · J8 OND

The 2015 Aston Martin DB9 presents a stable and consistently clean roadworthiness record. The most recent MOT, conducted on 15 January 2026 at 7,705 miles, passed with zero defects. This outcome mirrors every preceding test back to March 2022, indicating no recurring mechanical or structural faults have emerged over the documented period. The maintenance trend is stable and unbroken, with no advisories or failures recorded across five consecutive tests. The mileage accumulation is exceptionally low for a vehicle of this age. Between the March 2022 test at 5,597 miles and the January 2026 test at 7,705 miles, the car covered just 2,108 miles over nearly four years, averaging roughly 527 miles per year in that window. Earlier intervals show similarly modest use: 146 miles between March 2023 and April 2024, and 160 miles between April 2024 and February 2025. This pattern suggests prolonged periods of inactivity, which carries its own mechanical implications despite the low recorded mileage. Extended standing periods can cause flat-spotting of tyres, moisture accumulation in brake fluid and differential oil, and deterioration of rubber suspension bushes and seals through lack of lubrication cycling. A buyer should inspect the tyre sidewalls for perishing and dry rot, regardless of remaining tread depth, and check the brake fluid for water content. The front and lower suspension bushes should be examined for cracking or perishing, as these degrade with age and disuse rather than mileage alone. The underbody and subframe warrant close inspection for surface corrosion, particularly around mounting points and along welded seams, as standing vehicles can develop condensation-related corrosion in sheltered areas. The exhaust system, including catalytic converters and lambda sensors, should be checked for condition, as short-run use can accelerate internal moisture buildup. A pre-purchase inspection by a marque specialist is strongly advised to verify the integrity of the braking system, power steering rack, and drivetrain components that may have seen insufficient use to maintain consistent lubrication.
