2013 Audi S6 Prestige quattro 4dr Sedan AWD (4.0L 8cyl Turbo 7AM)
I traded my 2011 Audi S4 Prestige with drive Select on a 2013 S6 with the invovation package. Although the S6 was 30% more expensive than the S4, I consider it a bargain. It rides better, handles better, is faster, and is techincally much more advanced than the S4. It also gets just as good gas mileage. I have been driving Audi Quattros since 1987 and This is my eleventh one, so I do have considerable experience with the brand and know what I am saying when I say the 2013 Audi S6 is one awesome car.
