Jenny- I am restoring a 1987 Jaguar XJ-SC and have done a lot of research on the cars. Please send me a direct email at ghcunningham
comcast.net and I can share some information with you. -Gary
PS- From 1982 thru 1988, a total of 5,013 XJ-SCs were produced, but only 132 of them in 1988 alone. So yes, your car is quite rare indeed!
