What this means if you are buying a 2004 Yaris

The 2004 is a weaker year for this model, passing 14.9 points less often than the Toyota Yaris average. Some of that is simply age, so compare it against the 2004 figure for all cars above rather than against newer examples. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.

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 above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures. On a 2004 Toyota Yaris the average at test was 94,846 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 2021 at 94.1%, and the weakest in our data is 1999 at 61.8%. That 32.3 point spread across the model's life is why comparing a 2004 car against a newer one tells you very little.
