Hopefully not breaching the advertising rules of the site but you might wish to try Mike Rondot. I believe he may even be an occasional visitor to this site.
Examples of his work can be found
here
I have a couple of his works (prints sadly not originals) but fantastic all the same. Sorry, cannot give you any idea how much an original would cost but any of the Jag mateswho lurk these pages may have an idea - I would be very surprised if he hasn't been commissioned to produce an end-of-Jaguar painting.
Edited to add - just looked at the link and he has indeed produced a farewell to the Jaguar print!
