Every BMW 645 model year
Pass rates fall as cars age, so the only fair comparison for a 2005 car is other cars of the same age. The full run for the BMW 645:

|---|---|---|---|
| 2004 | 76.6% | 1,056 | 105,561 |

What a 21-year-old car fails on
A 2005 car is 21 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 above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust. On a 2005 BMW 645 the average at test was 102,036 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.
2005 is the strongest year on record for this model at 79.2%, ahead of every other year we hold data for.
