Expert verdict
Brakes: 1.3× the national share
Brakes make up 28.0% of everything recorded on the 2005 Aston Martin Db9, against 20.9% nationally — 7.1 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 72.4% and this one manages 91.3% — 18.9 points ahead of what its age and mileage predict.
- Failures here tend to be cheap ones. 65% of the repairs this model fails on cost under £30 in parts. The pass rate matters less than what a bad afternoon at the test centre actually costs you.

What fails a 2005 DB9
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2005 DB9
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the lights 1.5% of tests
“malfunction indicator lamp inoperative or indicates a malfunction”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
Check the coil springs 1.1% of tests
“coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
-
Check the windscreen 0.9% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

Across the 10 items that are recorded most often on this model, the average repair comes to £19–£58 — and 65% of those repairs are parts that cost under £30.

What testers noted without failing the car

| Tread depth below requirements of 1.6mm Tyres | Advisory | 6.7% | £45–95 |
