1982-1991 Jaguar XJ-S XJ-SC Service Repair Workshop Manual PDF VEHICLE/EQUIPMENT INTRODUCTION: The Jaguar XJ-S and its open-top variant the XJ-SC are iconic grand touring automobiles produced by Jaguar Cars from 1982 through 1991. Representing the pinnacle of British luxury performance engineering, these coupes and Targa-top convertibles combined elegant pininfarina-influenced bodywork with powerful V12 and inline-six powertrains. The XJ-S carried Jaguar into the modern era with refined suspension, advanced climate control, and sumptuous leather and wood interiors. The XJ-SC variant, introduced later, offered a semi-convertible experience with fixed rear side windows and Targa-style roof panels, appealing to enthusiasts who desired open-air grand touring. These vehicles are increasingly sought after as collectible classics, making comprehensive repair knowledge essential for preservation and restoration.
