I have owned this XJS for 7 years and the previous 10 years it was in a cocoon.
It has the AJ16 engine and all the classic extras from being the celebration model.
It has just passed its MOT and had a service with no issues and if a very nice and reliable example. It cruises along lovely.
I have had the following bits done in my ownership. New brakes and callipers, new headlining (classic fault now sorted), new battery, new alternator, coil, injectors.
I have priced it to allow for a couple of jobs that will need doing, if you want it perfect. The air con needs a new part, there is a little blistering on the door which I will try and get done soon, but just being honest in its current condition.
I am selling for personal reasons otherwise I would be keeping this for a few more years to appreciate.
