That was always my thought but wanted to check as I'm 100% certain that somewhere, written on something official, it references 'X-Pack'. The cloth interior and lack of most basic comforts implied otherwise of course, but I've read enough on here to know that some builds came off the factory line with some unique differences.....
The X Pack was only available on the V6 and added the heated/electric leather seats, the 6cd boot changer and metallic paint.
