Every BMW Z3 model year
Pass rates fall as cars age, so the only fair comparison for a 1997 car is other cars of the same age. The full run for the BMW Z3:
| Year | Pass rate | Tests | Avg mileage |
|---|---|---|---|
| 1997 | 71.1% | 1,621 | 93,411 |
| 1998 | 73.4% | 2,455 | 87,642 |
| 1999 | 74% | 2,708 | 88,969 |
| 2000 | 74% | 1,913 | 85,537 |
| 2001 | 74.7% | 1,774 | 81,397 |

What this means if you are buying a 1997 Z3
The 1997 is a weaker year for this model, passing 2.8 points less often than the BMW Z3 average. Some of that is simply age, so compare it against the 1997 figure for all cars above rather than against newer examples.

What a 29-year-old car fails on
A 1997 car is 29 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, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures. On a 1997 BMW Z3 the average at test was 93,411 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 2002 at 77.5%, and the weakest in our data is 1997 at 71.1%. That 6.4 point spread across the model's life is why comparing a 1997 car against a newer one tells you very little.
