I got a 2009 audi a4. This my first audi, and I dont know whats gonna happen in the future. Generally, so far its nice. But its true that many friends told me they spent on that fucking car a lot for fixing, especially B6 owners. The thing is what u like. Most students they dont know about the cars, and the only emphasis for them is "at least can work and dont get me in trouble". I compared lots of cars before I get my audi, e.g. 328xi, C-calss and IS 250. But I choose A4 cauz of its interior and torque. Buying a car in US for an international students is not easy. No matter whats ur choice, just remember, be patient and dont be rush. US dealers are the most dishonest business in the country(I was cheated by once on my civic).
