What this means if you are buying a 2018 340i

What an 8-year-old car fails on

A 2018 car is 8 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 2018 BMW 340i the average at test was 41,998 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.

2018 is the strongest year on record for this model at 93.3%, ahead of every other year we hold data for.
