No, I couldn't find any either. Turns out it's not one, but an XJR. Cousin who's been telling me about it says he doesn't get to see the back, just underneath or in the engine bay. As it's one of the saloons (XJ40 / X300, somewhere along those lines) I'm not that interested in it as a car. It's supercharged, not turbo. There is an impressive list of things they've tried so far - it goes into limp home mode after about 40miles, though this is getting shorter, sometimes as little as 10 mins driving. I've given him a couple of ideas, but these were based on the XJS V12. Thanks for the feedback Richard.
Cheers,
