if you go to jag-lovers.org you should download Kirby palms book on the xjs
its not fresh in my mind right now so i might be mixing it up a little but
its something like in 1988 the xjs won le mans so in 89 jag released a
special edition commemorative xjs in Europe
so in north America they released the classic collection
that's the basic idea

 

sorry to reply twice but i found the passage i was looking for

'"1990 LE MANS: Jaguar won again! Mansell: “The second Le Mans Special Edition was introduced at the Birmingham (UK) Motor show in September 1990 to celebrate the TWR XJR-12 win. Based on a standard car, the 280 models built had quad headlights, 16" lattice wheels, sports suspension, full Autolux leather interior, high-contrast walnut veneer, a four spoke leather steering wheel and Wilton carpets. The stainless steel sill plates had a 'Le Mans V12' motif along with the limited edition serial number.
North America did not receive the Le Mans but had their own Classic Collection instead. Along with unique paint colours, magnolia leather with contrasting piping, leather gearshift knob, charcoal toned leather steering wheel they also had gold boot and bonnet badges.”
Goodman: “Just a standard XJ‑S with SportsPack and spoilers.”
Brian Schreurs says, “There were 280 built for the world. No breakdown on Federal vs. ROW.”
