So I'm car shopping right now and I'm between an Audi A3 and a Subaru Impreza (5 door hatch/thing). Not exactly sure which one to get yet, but I have a question about the Audi. I want to spend somewhere around 25,000, so that means a slightly used Audi A3. Which years should I stay away from and which years were cooler (if any) options added?

Also how can I get my ipod to play on the stereo speakers, is there an aux port? Its kinda hard to find the little details. Many thanks.
