drove LS460 and liked the nav screen (bigger and brighter), backup camera, knee bags, etc, but also just returned from trip to vegas in my 02 LS430... 10 hours each way and feeling good at the end of the trip...looked down at speedo when moving with traffic and 90+ no commotion, just quiet with the miles ticking off. just cant trade it for the 460. love that big black 430. 460 was not as quiet...tranny was not as quiet and seemed "busy."
finally convinced my business partner to quit repairing m-bz and he got the LS 430 too.
