I wouldn't think twice about an Audi A4 wagon. I am a fiend for good snow cars and station wagons. On top of that, I have a great mechanic that only works on VW, Audi, and Porsche, so I want to be able to keep going there (at one point we took our Corrado there to get something worked on, I basically gave them permission to do approx. $1500 in repairs on it, they called me aaying all that I needed was $150 in repairs, very rare in the mechanics trade from my experience) The Corrado is getting a new clutch :| right now actually.
I don't care much for BMW's but that's just my opinion. Does BMW even still make the 325ix? I got to have AWD, and would love it if Subaru would make that little sporty Impreza in a wagon.
