Every BMW 6 Series model year

Pass rates fall as cars age, so the only fair comparison for a 2020 car is other cars of the same age. The full run for the BMW 6 Series:

What this means if you are buying a 2020 6 Series

The 2020 is one of the stronger years for this model, passing 4.4 points more often than the BMW 6 Series average. That is a point in its favour, though condition and service history still matter more than the model year.

What a 6-year-old car fails on

A 2020 car is 6 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 2020 BMW 6 Series the average at test was 38,581 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.

2020 is the strongest year on record for this model at 90.7%, ahead of every other year we hold data for.
