The XJ8 has broken interlock in transmission selector (not broken gearbox as advertised), often found after ignorant, ham-fisted wannabes wrench gear lever out of Park without first engaging footbrake. I bought it with its fault preventing any stick selection other than R, N, D . . . the broken internal bits stopping the stick from engaging P or any transit over to manual side of J-Gate . . . nowt other than one position fore and aft of where you see the stick here, in 'N', which allows start.
