The only car on this list I'd seriously consider apart from the S-Class is the Jaguar XJ, which would be a more patriotic option for me. I wouldn't have a 7-series (ugly) or Lexus or a Phaeton or the Cadillac or Lincoln (I don't think I could get them in England, besides they are no match for the rest of these cars). The Audi A8 is a fine car, but I've never found it as enticing as the Merc S-Class. And the Maserati Quattroporte is an exotic option but I still think I'd have the Merc.
