After I owned the vehicle for 5 months, it has 24.5 miles/gl for both city and highway which is very good for 270+hp vehicle. I don't know why people complained about it. I bought this vehicle for #1 safety priority. I hate when drivers follow me too closely when I drove Honda. Now, I can see people keep some distance behind me. I hope the Lexus symbol gives them a second thoughts. My 3 yrs daughter walks freely in the back compare to IS too tight. I gave up fun to drive for safety vehicle. I guess I am too young to drive this vehicle.
Sound system (even through the standard is not as good as Mark Levinson in my wife GX470), smart key system (it is very convenient when I carry my child and hands are full). Bluetooth, sun shade option,very quite ride, parking sensors.
Remove cigarette area for cell phone holder, DVD option behind head rest (requires for long distance with young kid). Not enough light in the back.
