Jaguar Sovereign (1988)
1988 Jaguar Sovereign
CarHunch analysed 131 real MOT records for the 1988 Jaguar Sovereign. Real test outcomes — pass rates, defect profiles, mileage data — from verified DVLA records. Updated as new MOTs are recorded.
The 1988 Jaguar Sovereign is a reliability concern: only 43.6% pass their MOT first time, well below the UK average of 80%, and 14.5% have recorded dangerous defects during testing. These are aging vehicles with relatively modest mileage (median 90,238 miles), suggesting the failures stem from age-related wear rather than hard use.
Expect to budget for repairs—the average car racks up 1.24 failures and 4.6 advisory items per test, pointing to recurring issues with older components and systems. If you're considering one, get a pre-purchase inspection from a Jaguar specialist and factor in regular maintenance costs, as these cars demand more attention than a typical 36-year-old vehicle.
