This time it is a Chevy Impala LT.

 Despite it is a mainstream family sedan, GM actually packed quite a bit of features into the car. It has an engine with cylinder deactivation system which shut off 3 of the 6 cylinders when the vehicle is crusing. The on board computer would show some rather decent gas mileage when the system is engaged. You can notice the engine switching between 3 and 6 cylinders mode if you pay attention to it, but otherwise it is rather unintrusive.

 The Impala also has a on board computer that is  common across most of the GM vehicles. It provides a wealth of information and control options, including tire pressure, remote start, cabin light diming control, etc.

 The audio system comes with XM radio and the controls are rather well organized. Again, it has text output that display station names and song titles, something Toyota and Chysler don't do.

Driven a Toyota Avalon. Engine smooth as silk with lots of power. Definitely a couple notches above the US Big 3. 

However, audio system still have cassette tape (when's the last time you  use one?) Besides, FM radio doesn't have the station ID and song title information like most of the GM cars do.
