Time to switch.  Got a 2008 Lexus ES 350.  Dark Grey, Black leather interior, nav system, etc.  Awesome.  Rides like a dream, plenty of power, and the nav system is awesome – when you are stopped, that is.  The one SERIOUS beef I have with the car is that Lexus has decided that I (or more importantly, a PASSENGER) is not capable of being safe, and does not allow input into the nav system while the car is in motion.  There is a whole movement afoot to try and change this.

Yes, there is a hack available, but it requires wiring changes.  I might have to do it.
