What this means if you are buying a 2018 S-Max

The 2018 is one of the stronger years for this model, passing 13.2 points more often than the Ford S-Max average.

What an 8-year-old car fails on

A 2018 car is 8 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 around average, so condition and service history will tell you more than the odometer does. On a 2018 Ford S-Max the average at test was 53,536 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 2020 at 86.4%, and the weakest in our data is 2006 at 58.9%. That 27.5 point spread across the model's life is why comparing a 2018 car against a newer one tells you very little.
