In case anyone cares there is a beautiful Supercharged XJ L at Galpin in Los Angeles. Went by to really check it out in person today.
They were very nice and pretty much let me mess with everything on the cars aside from driving it.

The interior is just stunning, they really got this right!
LCD screen is just amazing..surround cabin design looks so good in person

And I will admit the rear end is slowly growing on me.. slowly.

Some much more room in the rear cabin than on my 07 XJR
Jaguar has a winner on its hands.
