Used 2009 Audi A4 Values

Audi has upped the luxury performance-car ante with the 2009 A4. Its fresh face and benchmark interior distinguish it from its Mercedes-Benz C-Class and BMW 3-Series competitors, while its new dimensions also make it the largest car in its class. With the sure-footedness of Audi's world-class quattro all-wheel-drive system, more power from two new engines, the availability of both a wagon and a convertible, and the always-addictive oomph of the S4 model, Audi's sports sedan lineup has a little something for everyone.
