From the Jaguar Forum: (I am not the poster)

I maintain a register of all manual XJR6 cars on behalf of the Jaguar Enthusiast Club in the UK. I check a number of UK second hand car websites every week on the look out for these cars. Today I checked one of the major sites (Autotrader). There were no XJR6 cars for sale (auto or manual). This is the first time this has happened in all the years I've been checking this site. You know these cars are becoming rare when they are disappearing out of the second hand trade market. What is the experience in other countries?
