Buying a JAGUAR XJS?
Common problems tell you what can affect JAGUAR XJSs generally. VehicleScore® can check the history of the actual car you're considering.
Where does this data come from?
VehicleScore® analyses MOT histories from vehicles in its own dataset. Sample sizes vary by model, and a small sample is labelled as such. MOT data records roadworthiness and inspection defects. It does not capture every mechanical or electronic problem a car can have, and a comment on one test is not proof that the model has an inherent fault.
