Wow, that's a heavy job.. Good luck with it! I hope you have all the parts because it may be hard to scavenge the country(s) for all those missing parts..
I have a Fiat/Ferrari Dino that's going on Feebay in the next week that's in not much better condition than that. It was just way too much of a project to take on, so I'm giving the next lucky guy with the fortitude to take on a big project to step into the arena of classic exotic car ownership...
I saw a similar Jaguar shell for sale not too long ago on CL. If I remember, it was only about $2500..
