The only X-types I see around here are the ones at the Hertz rental lot. I don't think Jaguar did a very good job marketing the cars and or providing agressive lease or financing programs. Even then, there is the image which the marketing department didn't seem to focus on.
The european manual trans diesel model did make it around the Nurimburgring at under 10 minutes and that is impressive.
...maybe it was the S-type...
