After owning 3 LS430's 2 LS 460's IMO you will come to like the 460 so much better. The issue you mention does not sound to be a ride issue more of a 8 speed transmission issue. Yes if Lexus didn't add the 8 speed you might be complaining about the gas mileage, this is the main reason for the 8 speed. It is the hardest thing to get used to but after awhile you while you will get used to it. I found that S7 works well for me when cruising below 60mph. the good news is the steering and brakes are so much better than the 430 and the looks are great as BMW and Mercedes copied the look from Lexus.You will note that the 430 feels heaver than the 430 making for me a much more fun car to drive. For some reason I miss driving the 460 and find myself having to just go for a ride, never had that with the 430..
