Favourite Luxo-Barge - which is your pick?

[Sprintey]

OK, like the previous Ferrari or Lambo thread - except for long wheel base luxury.

Assume money is no object, don't worry about the woodgrain coming from clearfelled rainforests.

I'll start off - Jaguar XJ LWB, the generation from 2009 onward or so (X351). Incredible interior and dash design, bold and successful breaking from traditional styling. My grandad always had an XJ6, so this is my choice over much more opulent cars like the Bentleys and Rollers.

(My smarter choice: ZC 351 Fairlane, more simple and probably will go up rather than down)

What is your all time luxo-barge?
