7: Audi A6
Sometimes you want more than a compact car, and the Audi A6 is a large and in-charge luxury sedan. No matter which version of the A6 you pick, the car offered stellar performance for the price. The interior is spacious, and the styling of the A6 is timeless when you compare it to other full-sized sedans in this segment (via New Car Test Drive).
Living up to the Audi heritage is not an easy task but the A6 did it quite well. The car drives great and can make a great deal if you have been yearning for a true performance car. Although most enthusiasts will go for the S4 or the TT, the A6 is often the understated variant of the Audi lineup.
