Hello Bone. Thanks for the warm welcome. LOL
The word "quirks" was obviously the wrong word. What I should have said: I was going to have some major maintenance done at 54,000 miles and was looking for any maintenance recommendations that might not be obvious to some.
Example: Since my first post above, I've learned to have the so called Devil hose inspected. Apparently, the intake manifold has to come off to get access to the hose. Items like this. My introduction was simply lazy and incoherent. My apologies. Hope we can start over. LOL
Meantime, I've been reading the interesting responses from Spectre and Ford CrusherGT ref the Jaguar XJS. And have learned a lot from here and another Forum. Most helpful.
