Had a 92 XJS V-12...traded it for the SL we now have.
Truthfully, the V-12 was sound mechanically, but the electrical anomalies and A/C was what killed my appeal for the car.
It ate lamba sensors on a regular basis, had to replace the cruise computer, dash lighting, and replaced hoses, reciever, drier, only to be faced with a failed evaporator!
The only caution I received from fellow Jag owners was to NEVER let that V-12 overheat! It was well-documented that the engine would drop valve seats under that scenario!
