This looks quite nice actually. According to wikipedia, jaguar built 500 XJR 100s out of about 16,000 XJRs between 98-2003. The XJR 100 takes the XJR and adds painted trim, 19 inch wheels, big brembos, and red stitched steering wheel and shift knob. I think it might be a specific exterior/interior color package too.
