Buying and owning a 10-20 year old British car, even a Jag X350, is an exercise in record keeping. Asking the owner when they did what is a good start. Then recording what you did is better. I created a spreadsheet based on Jaguar factory recommendations, independent shop recommendations and forum advice. As you can see, it is incomplete. It needs frequencies added, as well as part numbers and web pages where parts can be purchased (preferably with global mail order at reasonable shipping prices). I am sure it also needs other areas where Jag X350 / X358 have weaknesses. I did not include anything for supercharged or diesel because my X350 is neither. Feel free to add.

If you want to contribute, I attach the spreadsheet to this post, include a screen shot for quick view and alternatively you can email me and I will give you editor status for https://drive.google.com/file/d/1Smj...ew?usp=sharing where I have uploaded the spreadsheet so multiple people can work on it. At one point, the administrator may want to make this a sticky if it is deemed worthwhile.
