My father and I went a purchases this car at an auction. The car has been very great to me, we bought it in August 2014 with 130k miles. I've been in a car accident with it in which I rearended a much larger vehicle at 45 MPH. Luckily I was super safe and I just had to replace the front bumper. The car has about 145k miles on it currently and it just seems to be falling apart. Plastic pieces in the exterior, the window regulator not working correctly and some oil leaking. It has been a very nice car and I am looking for a newer mode with less miles because I feel so safe in it. Also last note the quattro all wheel drive is amazing, you never feel like you don't have traction

Reading one of the reviews below, I had to express my agreement that you should steer clear of this car. I had a similar experience in purchasing a used 2005 A6 Quattro 4.3. It is still a good-looking car today and fun to drive. The problem of course is the cost of maintaining this vehicle. This is the only vehicle that I've ever owned that develops new mechanical or electronic issues while it is sitting on the street unoccupied. I've taken it in for so many repairs, I've just about shelled out the $5K that I paid to purchase the car two years ago. The "Oil Pressure low" warning light is on again. I have to get this car running well enough to sell to some other sucker.

Bought car CPO from a dealer. Used to own a 2004 A4 3.0 Quattro and fell in love after test driving the A6. Although used, general build quality is great and car drives smooth

Took delivery of 2005 A6 4.2 last fall. To date, there has not been one problem. The sport suspension is quite stiff with the 40 series tires. The engine is strong. My mileage is a mixture of highway city averages about 22 MPG every week.

I bought my A6 with 23000 miles in Nov. 08. Have never regretted it. Previously owned a 1998 A6. Wow, what a difference in performance and ride. The MMI system took some getting used to but is no problem once you figure out the logic behind it. I have had only one problem so far -- the memory for the seat and mirror settings was not working. It was a software problem that was fixed by the dealer under warranty. The handling of the vehicle is superb. Acceleration is smooth and very responsive. Surprisingly, the fuel economy on the highway is also very good for vehicle this size. In my trip to work (21 miles with 90% highway and 10% local), I typically get between 27 and 28 mpg. Local is 19.
