I had two 300s before I bought the Dart after a divorce. The 300s were good cars, but talk about rattles, they both had them after a year horribly. My particular Dart is much better and was way cheaper then them, when it comes to build quality. I don't know about the Aero, as I have an SXT. Rock solid so far. I have rented a Corolla and Sentra. I would not take them if they were given to me. Talk about rattle traps.
