Pass rates fall as cars age, so the only fair comparison for a 2003 car is other cars of the same age. The full run for the Subaru Impreza:

What this means if you are buying a 2003 Impreza

The 2003 is a weaker year for this model, passing 2 points less often than the Subaru Impreza average. Some of that is simply age, so compare it against the 2003 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 23-year-old car fails on

A 2003 car is 23 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 and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust. On a 2003 Subaru Impreza the average at test was 108,784 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 2018 at 90.1%, and the weakest in our data is 2007 at 75.5%. That 14.6 point spread across the model's life is why comparing a 2003 car against a newer one tells you very little.
