    Most enjoyable vehicle I've ever owned

    This car is one of a kind. Never would have owned a Audi,BMW,Mercedes Etc. unless this specific opportunity came up and I love it. Definitely a head turner no matter where you take it. Not to mention it gets up and goes in those certain situations when you need it the most.

    Best combo of price and performance out there

    Compared to an A4 the A6 has much more room and feels more solid on the road while maintaining classic Audi performance. I've driven Audis all my life and would recommend them to any driver looking for luxurious fun.

    2004 Audi A6 2.7T S-Line my first love

    I owned a 04 a6 and absolutely loved it. Very reliable and a blast to drive in the winter. Car has just enough power and decent gas mpg if you drive civil. Lol. Highly recommend. I will say if you don't have money for the maintenance forget it. These cars are beautiful machines and are expensive to work on. Absolutely worth it tho. I bought it certified preowned from the Audi Exchange and I'll never buy another brand. Bought to buy another one

    Great first fast car

    This is the first fast car I've owned, and its a great beginning into an expensive addiction. The only downside to this car is it underpowered from the factory, but a couple simple bolt ons and a tune up will really open it up for some fun!

    Audi A6 Quattro

    Comfortable luxury along with great dependability. Sneaky fast on the highway from 50-70mph. My fave among the German auto makers.

    Greatest wagon I've ever had

    Where to begin... my 2004 Audi A6 wagon was a tank, it took a large branch to the roof, no damage except a smashed rear window. The rest of te car was PERFECT! Not a scratch, dent or any other kind of visual damage! It was purchased used with 35,000 miles or so on it, I sold it with 175,000 plus miles on it. Yes I had my fair share of issues, but nothing serious enough to kill the car. Brakes were the main problem. She was always burning through her brakes and tires due to my use of her, but the engine was a work horse. Not one did the engine fail me. It worked through everything and anything. I put the car through abuse and it took it like a champ an came out on top! I would love to have another Audi as great as my A4 wagon.

    2004 A6 2.7 Quattro w/ S-Line trim - I love it.

    I got this car with higher miles, but other than normal maintenance and wear n tear, VW/Audis are among the most reliable cars on the road. The twin turbo is dangerously quick. The car rides so smooth and even 13 years later, is still nicely equipped and faster than most other cars ! Heated front and rear seats, in dash cd changer. my only complaint is the design flaws of the center console and drivers LCD display both broken from prior owner and a real leather OEM replacement is $300 and the tiny LCD replacement is another $300

    most reliability i have owner

    After driving the Audi A6, and several others, the Audi V6 was by far the best value for my money. It is solidly built, quiet, and smooth. The ride is like a Lexus and it handles almost like a sedan. It's just the right size, has very comfortable seats and is loaded with technology! On my first 500+ mile trip, I averaged 28.8 mpg. If you're looking for a new in this segment, put this one on your short list to test drive.

    This model of car is good on driving, but a little expensive fix fee when there is a big problem on car. Audi A6 needed more gasoline compared with Japanese car or American car.
