After driving the LS460 I felt exactly the same as you. I like my '04 LS430 just as well. When they say it has 100 more hp. I dont know where those horses are. Then, when they wanted list for their car and offered me $2000 less than Carmax would give me for mine, I walked. And, they could care less. This is the 9th Lexus I have bought from this dealer. Customer loyalty means nothing to them.
