Scott, As I said, if it isn't on you won't be missing much, as it loses it's affect. My XJ Supersport being a Jag directors car had every single extra going , three TV's (agree with Peter on that) Jaguar voice (also agree with Peter). Bower and Wilkins 1200 watt 20 speaker sound system (fantastic), double glazing, and best of all a 5 litre supercharged engine , which was miles faster than my Aston Martin DB9 . The XJ is a truly fantastic car and I'm sure you will be delighted with it . The only reasons I got rid of it was to stop the wife whining, as she said it didn't look like a proper Jag, and also it was too big for our cart tracks out here in the sticks ATB, Trevor
