i want to acquire an s-type jaguar sedan, please, i need advice on how to maintain it, what are the likely problems i am going to face while using it? how can i get the parts if needed? thanks for your help.

It's been known for more than 50 years that you don't buy a Jaguar for reliability. Jaguars are unpredictable and you are better off with having one along with other vehicles. If you decide to own one, be sure to convert the mechanical tensioner to hydraulic. That will be one-problem-too-many that will be taken care of. You cannot profile a Jag in terms of reliability.
