Pass rates fall as cars age, so the only fair comparison for a 2013 car is other cars of the same age. The full run for the Mercedes-Benz Gl:

What this means if you are buying a 2013 Gl

The 2013 sits close to the Mercedes-Benz Gl 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 13-year-old car fails on

A 2013 car is 13 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 above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust. On a 2013 Mercedes-Benz Gl the average at test was 101,230 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 2014 at 86.8%, and the weakest in our data is 2007 at 80.9%. That 5.9 point spread across the model's life is why comparing a 2013 car against a newer one tells you very little.
