How can i get my hands on a manual for this car online or a harcopy?

e-bay,there are several.

You can search the web and various sites like ebay, jagbits, etc., (if you are just looking for an electronic version most can be found via jagrepair's site), OR you could contact Jaguar directly and purchase one through Jaguar's website and/or via Jaguar's support number that is listed on their website.
