2008 Aston Martin DB9 5.9L Petrol · LM51 AML

The 5.9 L V8 petrol engine of this DB9 typically delivers around 12‑15 mpg, leading to relatively high fuel expenses, especially given the vehicle’s weight and performance focus. The annual Vehicle Excise Duty is likely in the highest tax band (Band G), adding a substantial fixed cost, while the insurance group is expected to be in the high‑40s, resulting in elevated premiums. Typical maintenance costs are also significant, with specialist parts and labour for suspension, brakes and routine servicing pushing the annual outlay to roughly £1,200‑£1,500 when fuel, tax, insurance and average upkeep are combined.

Begin by examining the shock absorbers for any signs of oil leakage or reduced damping, as the MOT history shows repeated major fluid leak failures; a visual inspection and a bounce test can reveal worn components. Next, inspect the brake discs and pads for scoring, pitting or excessive wear, and verify that the brake fluid is clean and at the correct level. Check that the registration plates are the correct size, securely mounted and fully legible, and look for any fading or damage that could cause a future MOT failure. Finally, scan the under‑tray area for rust or corrosion, especially around the areas noted in the 2013 advisory, and assess tyre condition, suspension bushings and overall bodywork for any signs of wear or damage. Review the complete service history to confirm that all recommended maintenance items, such as oil changes, cambelt replacement and suspension component renewals, have been carried out on schedule, and ask for documentation of any repairs performed after the major MOT failures in 2014, 2018 and 2021. A thorough test drive should also be undertaken to listen for unusual noises from the suspension or drivetrain and to gauge the overall responsiveness of the vehicle.
