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.
