Every Mercedes-Benz R-Class model year

Pass rates fall as cars age, so the only fair comparison for a 2010 car is other cars of the same age. The full run for the Mercedes-Benz R-Class:

What this means if you are buying a 2010 R-Class

What a 16-year-old car fails on

A 2010 car is 16 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 high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself. On a 2010 Mercedes-Benz R-Class the average at test was 125,720 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 2011 at 78.1%, and the weakest in our data is 2006 at 71.2%. That 6.9 point spread across the model's life is why comparing a 2010 car against a newer one tells you very little.
