is this a joke? the LS430 steals a lot of cues from the German manufacturers...those headlights came right off the last gen W220 chassis S-class
the new Lexus are definitely refined though -- and unlike Audis and BMWs, you dont get raped by major depreciation. They tend to hold their value pretty well, like the flagship Benzes
if you want a purely highway cruiser car with straight line acceleration you will go for the S63 AMG. We could talk Rolls and Bentleys too, but lets not get carried away too much.
p.s. the LS430 is obsolete, they dont make em anymore. Now they make the LS460
