I’m a new Jag owner … 91 XJ40.
I just drove this car up the interstate to a work meeting 30 minutes away, and then back home on the back roads, and it was pure joy.
Well, except for two things: The AC doesn’t work so I had to go windows-down (which I don’t mind personally, but most passengers would), and when I stop at a light the oil pressure drops to zero and usually the oil dummy light comes on (I’ve recently started ignoring this as there seems to be no other indication of any issues, plus I’ve read about some sensor issues that are harmless).
There are other issues, like the occasional transmission light and limp-mode issue that seems random and usually goes away upon a stop and re-start of the engine, but nothing else really bothers me much.
If you are an XJ40 person in the Atlanta area and you would like to have a beer sometime, please let me know … I’m buying.
(Edit: Whisky works, too.)
