Erik this is fantastic cheers! I managed to find info and identify about sixteen cars before this, but you're right, it's gonna be practically impossible to get them all right. Especially the Japanese ones. I've gotta find out more about the XJR-15LM, I've seen photos of two of them in Japan which won't help at all. Your picture of the green one is another new one I think. Apparently they've got 7.4 litre engines with more than 700bhp. I have a lead on race number #7, it's just whether I can really bring myself to start emailing former owners and so on, it looks like race number #17 was the same car as well. I'd love any more photos you've got, can never have too many photos of the XJR-15 eh?
