Every Mercedes-Benz Gla model year

Pass rates fall as cars age, so the only fair comparison for a 2014 car is other cars of the same age. The full run for the Mercedes-Benz Gla:

What this means if you are buying a 2014 Gla

The 2014 is a weaker year for this model, passing 2.5 points less often than the Mercedes-Benz Gla average. Some of that is simply age, so compare it against the 2014 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 12-year-old car fails on

A 2014 car is 12 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 a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age. On a 2014 Mercedes-Benz Gla the average at test was 76,245 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 2014 car against a newer one tells you very little.
