Every Daihatsu Sirion model year
Pass rates fall as cars age, so the only fair comparison for a 2006 car is other cars of the same age. The full run for the Daihatsu Sirion:

What a 20-year-old car fails on
A 2006 car is 20 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 a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age. On a 2006 Daihatsu Sirion the average at test was 77,834 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 2009 at 71.3%, and the weakest in our data is 2005 at 64.7%. That 6.6 point spread across the model's life is why comparing a 2006 car against a newer one tells you very little.
