The 04 XJ8 is at 100k and thanks to the great threads and advice on this forum, I've successfully swapped out the plugs and the coolant reservoir. The Jag is running great and I don't want to go crazy with preventative maintenance, but is there anything else I should consider at this point in time? I've been reading about the transmission fluid thread and am looking to get that done at a local Indie shop - my DIY skills have limits.

Part of the 100k package was a hand wash and I've got to say - Jaguar really outdid themselves in terms of paint quality. Even after 8 years this car turns heads!

 

A look at the Owner Service Book for what is done each year (or service) may give you some hints. If you maintained each year, you should be on the 8th service.
