2002 Audi A6 Quattro Reviews
I purchased a 2002 A6 Quattro witjh 164K miles. It needed a battery when I purchased it and after replacing the battery, I went to Auto Works and have a free diagnostic done on the vehicle and determined that I needed an alternatoer. Other than this repair I have had no other issues with this car. Best investment of 4K that I could have made.
I wish I had found an Audi before the other vehicles I owned.
Not a great car.
