Audi A6 for Sale Audi A6, year 2009/ for sale. I am selling the car because I want to buy a 7-seater vehicle. The car is in very good condition and has had full service done. All oil and filters have been changed recently. It also has a brand new timing belt and a new alternator belt, both recently replaced. All services are up to date, so the next owner will only need to put diesel and drive without worrying . If you are interested, feel free to contact me for more details.
