Every Jaguar Xjs model year
Pass rates fall as cars age, so the only fair comparison for a 1990 car is other cars of the same age. The full run for the Jaguar Xjs:
| Year | Pass rate | Tests | Avg mileage |
|---|---|---|---|
| 1990 | 81.7% | 334 | 78,606 |
| 1991 | 84.4% | 231 | 81,677 |

What a 36-year-old car fails on
A 1990 car is 36 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 a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age. On a 1990 Jaguar Xjs the average at test was 78,606 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 1995 at 87.2%, and the weakest in our data is 1992 at 75.6%. That 11.6 point spread across the model's life is why comparing a 1990 car against a newer one tells you very little.
