If you are looking or a true luxury large car with lots of room at a reasonable price, this is it. Not another competitor can come close and you get it with Toyota reliability and quality. Styling could be improved but if Toyota did that then there truly is no reason to buy a Lexus LS. Seems same reasoning went into nav system. Portable GPS has touch screen for less than $200 now. This one doesn't. Lexus GPS does. If Toyota cleaned up a few very low cost details there would be no reason for the Lexus brand. Toyota's challenge is keeping the "goodness" of this product away from their prospective Lexus customers.
Large backseat. Real people fit and fit comfortably. You'd think you're in an early 70s Cadillac rear seat.
GPS needs to be touch screen. Jazz up the styling.
