I bought the car new. It is a wonderful car to drive although I have had a number of electrical and mechanical problems. I have severe arthritis and the seats are the most comfortable of any car I've ever owned and adjustable to many positions. I love the power and the instant response and feel it is the safest car on the road today. The only reason I'm considering another make is reliability. I've never owned a car with so many problems.
My favorite features are comfort, superior sound system, looks (at almost 7 years old it still looks great... I like the lines better than the newly designed 2007!), driveability (instant response, stability), safety features.
