His biggest complaints were it wasn't much more frugal with its five speed box, amd it just doesn't 'feel' as high quality...I can't comment, never even been in a 430... I do prefer the look of the ls400, it seems lower, wider, less slab sided, but hey, neither are in the same aesthetic league as an x308 jag or the like, to my eyes...a lexus is a car to be enjoyed from behind the wheel in a manner I have never experienced in owning almost 200 cars..yeah, you read that right..
