Every BMW 520 model year
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 BMW 520:

What this means if you are buying a 2013 520
The 2013 sits close to the BMW 520 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 high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself. On a 2013 BMW 520 the average at test was 117,620 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 2016 at 87.6%, and the weakest in our data is 2002 at 65.7%. That 21.9 point spread across the model's life is why comparing a 2013 car against a newer one tells you very little.
