After a year with this car, it has been very dependable. However, like with most other owners, the side wind noise drives me batty. And calls to Lexus say that it is a design problem, that nothing can be done about it, and the problem won't be addressed until about the 2011 model year. Bummer. Also, the complete lockout of nearly every navigation feature while in motion renders the system nearly useless. Don't waste the money on this. Buy a Garman instead.
Excellent sound system when the wind noise doesn't overpower it.
Fewer doodads that I rarely use and concentration on the basic comfort and quality issues. Front seat does not have a tilting seat... only up and down and back and forth. Just the back tilts. I like to be able to adjust in this way and expect it on a car this expensive.
