Just depends on how much money you want to spend. I paid 26, 490 plus tax and license for mine. It's got everything on it, including stability control system, side airbags. The only thing I miss is seat memory settings for driver. Don't know if you can get Audi, BMW similiarly equipped for that price.
in my opinion, new a4 1.8T's are severely underpowered. so whatever you do, don't go for that. they also handle like shit, definitely not up to the european sportsedan standards. im in a bit of a similar situation. i've narrowed my choices down to '04 5spd 9-3 arc and '04 6spd tsx... test drove both, liked both... tsx has cool navi, 9-3 doesn't. 9-3's turbo'd, tsx isn't... this goes on forever.
i'd also appreciate your thoughts and opinions and help me decide.
