This car is awesome. it looks amazing driving down the street. I even got a complement from a Mercedes owner. The STS drives great and I love the cruise control that slows down when you get too close to another car. The heated/cooled seats are great for any weather. The navigation screen is big and easy to see even when the sun is out by moving the screen back and forth.
I like how you need the key fob in order to start the car so it makes it harder for people to ride away with it. I also like the heads up display for the driver.
The manual and the trunk button and the rear seat cup holders. They need to change where they show the temperature outside to the navigation screen instead of the drivers info center.
