This is a very fun car. I traded my 2001 GS300 for it. It has plenty of power, although it's deceptive due to the trademark quiet, smooth ride of Lexus. It handles very well without a tremendous sacrifice in ride quality. The car has a lot of great features, especially if you get the NAV package. It would be a waste to buy this car without it due to the bluetooth and back-up camera that come with it, among other things.
Hard to say because there are so many. The bluetooth phone is amazing and was very easy to set up. My wife has commented that she can't even tell that I'm not talking directly through the phone when I call her on it.
The location for the power plug in the center console is in a strange location. I will try to find a shorter adapter, but at this point I can't plug it in without having the center console open.
