This 2016 Audi S6 boasts relatively low mileage and nearly $20,000 in factory options, including Prestige, Sport, Driver Assistance, Comfort Seating, Cold Weather, and Black Optic packages. It features performance modifications such as an APR Stage 1 tune, APR TCU flash, and oil screen relocation, and comes with a clean, accident-free Carfax report. The exterior shows some chips, scratches, and curb rash on one wheel, with wear noted on interior touchpoints.
