This has been a great car and a real bargain. Mine was purchased as a low mileage certified car and is still flawless after over 100k miles driven over some very rough Detroit freeways. I have every option including sunroof, factory chrome wheels, rear sunshade, and Bose system...and every thing works. The dealer has replaced small items like the headlights under warranty and has done a good job of normal maintenance without ever overcharging or suggesting unnecessary service [I've owned a BMW 6 Series that always needed expensive service]. The ride is firm enough without being harsh...good even over Detroit's rough roads, and the steering is still tight. MPG = 28 highway at 75 MPH+
Ride and handling are still good when fully loaded with passengers and luggage, due to automatic leveling [no ugly squat].
The new 3.6 direct injection CTS V6 with 300 HP would be great, but an expensive upgrade.
