Expert verdict
Tyres: 1.4× the national share
Tyres make up 28.3% of everything recorded on the 2012 Aston Martin Db9, against 19.8% nationally — 8.5 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- 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 77.2% and this one manages 90.7% — 13.5 points ahead of what its age and mileage predict.
- Failures here tend to be cheap ones. 59% 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.

The twenty areas with the most Aston Martin DB9 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2012 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 2012 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 windscreen 3.4% 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.
-
Check the lights 1.7% 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 wipers and washers 1.3% of tests
“washers not working”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
