Just DD it. I daily drive mine and commute from the Tysons' area to Rosslyn for work. Bought it new in 2008 and now it has 62000 miles. No major problems so far *knocks on wood*. It's a pretty solid car. My advice to you for keeping the car in shape is to keep up with the maintenance and drive it on the highway whenever you can. The stop and go traffic coupled with the unnecessary potholes in the Rosslyn-Clarendon-Ballston area makes my car feel like its hurting every time I drive through that horrible area.
