I just bought my 2008 LS and am extremely impressed. The two things that absolutely stand out are the following: interior styling and fit and finish, and the smoothness/quietness of the ride at any speed. Clearly Lexus is well known for both of these attributes but on a daily basis they continue to impress. I shopped the 7, S550, A8 and all of them are very fine cars but none of them though outdo the LS is the aforementioned categories. AND - the LS is 20k less than all three of those models. Bottom line : An extremely fine vehicle in every sense that tries not to scream "I am rich".
Interior, smooth acceleration, Mark Levinson audio, navigation, styling.
I added the "touring" wheels to my short wheelbase at extra cost. They should make this an option instead of an accessory.
