What this means if you are buying a 2019 Gla

The 2019 is one of the stronger years for this model, passing 3.1 points more often than the Mercedes-Benz Gla average. That is a point in its favour, though condition and service history still matter more than the model year.

What a 7-year-old car fails on

A 2019 car is 7 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 below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck. On a 2019 Mercedes-Benz Gla the average at test was 37,724 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 90%, and the weakest in our data is 2015 at 82.4%. That 7.6 point spread across the model's life is why comparing a 2019 car against a newer one tells you very little.
