What this means if you are buying a 2004 Db9

The 2004 is a weaker year for this model, passing 4 points less often than the Aston Martin Db9 average. Some of that is simply age, so compare it against the 2004 figure for all cars above rather than against newer examples.

What a 22-year-old car fails on

A 2004 car is 22 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:

  • Lights and electrical: 10.36% of all cars tested
  • Suspension: 8.65% of all cars tested
  • Tyres: 6.23% of all cars tested
  • Brakes: 6.1% of all cars tested
  • Visibility: wipers, washers, glass: 4.65% of all cars tested
  • Body, chassis and structure: 3.18% of all cars tested

That is around average, so condition and service history will tell you more than the odometer does. On a 2004 Aston Martin Db9 the average at test was 52,255 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.

The strongest year for this model is 2015 at 95.6%, and the weakest in our data is 2004 at 87.7%. That 7.9 point spread across the model's life is why comparing a 2004 car against a newer one tells you very little.
