Just awesome
Bailey Boy, 08/23/2020
2020 Audi S6 Premium Plus 4dr Sedan AWD (2.9L 6cyl Twincharger gas/electric mild hybrid 8A)
Just got my S6 2 days ago. I've had a lot of cars, but this is my first Audi. This car is a blast to drive. Very fast, sharp handling, but comfortable ride. Quality seems impeccable. Electronic interface is superb, interior is gorgeous, and exterior is also beautiful. Perfect car for me.
