1976 Jaguar XJ12L, 111.000 miles, runs rough, registered 2015

This was purchased as a project a few months ago for a nice group of young scientists to fix up and drive. They learned that it is hard to fix a jaguar. They tell me it sounds amazing and beautiful when it runs. but it can be tough to start right sometimes. The car is a perfect fixer-upper. all the core parts like the engine. transmission. power steering. breaks. etc work really well (as far as we know). but most of the lights/windows don't work and the radiator has a leak. It will probably need to be towed to you. Body in great shape. Beautiful car. Comes with an awesome manual and various parts. Registered for 2015. Could fix it up? Use for parts?
