Every BMW 635 model year
Pass rates fall as cars age, so the only fair comparison for a 2008 car is other cars of the same age. The full run for the BMW 635:
| Year | Pass rate | Tests | Avg mileage |
|---|---|---|---|
| 2008 | 78.2% | 510 | 130,076 |
| 2009 | 77.5% | 404 | 122,799 |

What an 18-year-old car fails on
A 2008 car is 18 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 2008 BMW 635 the average at test was 130,076 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 2010 at 79.7%, and the weakest in our data is 2009 at 77.5%. That 2.2 point spread across the model's life is why comparing a 2008 car against a newer one tells you very little.
