Pass rates fall as cars age, so the only fair comparison for a 2004 car is other cars of the same age. The full run for the Mercedes-Benz E:

What this means if you are buying a 2004 E

The 2004 is a weaker year for this model, passing 7.7 points less often than the Mercedes-Benz E 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 very high mileage. Clutches, dual-mass flywheels and head gaskets have usually been through at least one repair by this point, so ask for evidence rather than assume the car is original everywhere. On a 2004 Mercedes-Benz E the average at test was 140,580 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 88.8%, and the weakest in our data is 2005 at 71.7%. That 17.1 point spread across the model's life is why comparing a 2004 car against a newer one tells you very little.
