2021 Aston Martin DBX V8 Auto 4.0L Petrol · LL70 FDV

A spotless two-test DVSA record across August 2024 and August 2025, both concluding with a pass and zero advisories on either occasion, establishes this DBX as one of the cleaner high-end performance SUVs on the used market from a roadworthiness perspective. With no recorded brake, suspension, tyre, exhaust, or corrosion advisories over consecutive tests, there is no documented pattern of component wear to investigate or budget for in the near term. The latest examination on 11 August 2025 confirms that the car was presented in compliant condition less than a fortnight into its fifth year, and the absence of any carry-over items between tests suggests the vehicle has not been masking developing faults. Mechanically, the public MOT profile is essentially a non-issue for this particular car. At 10,267 miles against a five-year age, the annual accumulation works out at roughly 2,053 miles per year, which is exceptionally low for any motor vehicle, let alone one of this calibre and list price. Such a figure points strongly to the car having spent significant stretches stationary rather than being used as a daily driver or long-distance tourer, which carries its own set of mechanical considerations even when road tests return a clean sheet. Components that suffer most from prolonged standing rather than active use — the air-conditioning compressor and refrigerant circuits, the brake calipers and pistons that can seize against corroded discs, the engine and gearbox oil seals that can mist when not regularly exercised, the 12V battery which degrades through repeated deep discharge cycles, and the various rubber boots and flexible hoses that harden without periodic flexing — will not necessarily have been examined in detail during a standard MOT. The mileage progression between the 2024 and 2025 tests would also be worth confirming on the V5C and service invoices, as a near-identical odometer reading across two consecutive tests would confirm extended periods off the road. On a physical inspection, particular attention should be paid to the brake system, which is the most common casualty of low-mileage use on high-performance vehicles. With the wheels removed, examine the inner and outer faces of all four discs for surface corrosion, lipping, or pitting that could indicate the calipers have been binding against stationary rotors. The brake fluid should be checked for colour and water contamination, and the flexible brake hoses inspected for any surface cracking or perishing, particularly where they pass near the heat-load undertrays. On the test drive, listen for any scraping, grinding, or dragging noise from the wheels on the first few applications, and feel for a spongy or uneven pedal response that would warrant further attention to the hydraulic components. The front and rear suspension should be exercised over speed humps and uneven tarmac, listening for any clonks, knocks, or squeaks from the wishbones, anti-roll bar linkages, and top mount bearings that could indicate dried or perished bushes given the limited mileage accumulation. Beyond the braking and suspension items, the buyer should satisfy themselves on the condition of the engine and drivetrain fluids, as these degrade through age rather than mileage. Request evidence of recent oil and filter changes, coolant renewal, and transmission fluid service, as a service history dense with mileage but light on calendar-based intervals can still leave a four-cylinder or V8 prime for internal corrosion or oil-misting issues. Inspect the undertrays, engine bay, and around the turbochargers or oil filter housings for any signs of seepage or staining that would warrant further investigation. The tyres should be examined for both tread depth and, critically, sidewall condition, as tyres older than five years can suffer from cracking and hardness even with unused tread, and the original-fitment Pirelli P Zero or equivalent items on a DBX of this vintage will be approaching that threshold. Finally, a battery health and charging system test using a diagnostic tool should be carried out, as a chronically discharged or weakened 12V battery is the single most common cause of non-start issues on low-mileage prestige vehicles and would not have been flagged on either MOT pass.
