Every SEAT Leon model year

What this means if you are buying a 2017 Leon

The 2017 is one of the stronger years for this model, passing 4.5 points more often than the SEAT Leon average. That is a point in its favour, though condition and service history still matter more than the model year.

What a 9-year-old car fails on

A 2017 car is 9 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 2017 SEAT Leon the average at test was 63,469 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 87.7%, and the weakest in our data is 2006 at 64.7%. That 23.0 point spread across the model's life is why comparing a 2017 car against a newer one tells you very little.
