Purchased in Sept. My first Lexus and am still excited to drive it everyday. Very quiet and comfortable and it has plenty of gadgets. The sound system is unbelievably good. I am currently getting around 27 mpg, mostly highway. I haven't had any problems or have had it serviced yet and so a good service visit will put it over the top.
Mark Levinson sound is number one followed by all the other gadgets.
When you switch modes (ex: map to audio) it always reverts to prior mode, I would like it to remain in the mode that you are working in.
