Every Ford Mustang model year

Pass rates fall as cars age, so the only fair comparison for a 2020 car is other cars of the same age. The full run for the Ford Mustang:

What this means if you are buying a 2020 Mustang

The 2020 sits close to the Ford Mustang average, so there is no strong model-year signal either way. Judge the individual car on its own history. 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 6-year-old car fails on

A 2020 car is 6 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 low mileage, which usually means light urban use. Short journeys are harder on batteries, brakes and exhausts than motorway miles, so do not assume low miles means low wear. On a 2020 Ford Mustang the average at test was 19,064 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 89.6%, and the weakest in our data is 2016 at 83.5%. That 6.1 point spread across the model's life is why comparing a 2020 car against a newer one tells you very little.
