If you want to redo some parts of your interior (but it's worse than simply needing a repair kit), go to your local fabric store and see what they have to offer.

I'm going to redo most of the interior of my XJ12, and after I priced it all out (including headliner material, cotton-backed vinyl for the door panels and center console, the same type of vinyl for the top of the dash below the windshield, and the 2 different spray adhesives), it came out to just over $100. Buying all of the parts already done (headliner, interior door panels, dash top, etc.) would come out to almost $1000.
