  Purchased Used with 62k miles - 2004 Audi A6
  By charbojr - January 8 - 11:56 am

  Bought this off the lot with 62k miles on it. This will be my daily driver. Purchased for its all weather capability and european refinement. For a 10 year old car this one is in fairly good shape. Some gremlins do plague the car, phantom sunroof, power steering pump went in the first 20 days and driver side rear window does not work. But this is part and parcel for a 10 year old car. It is also a heavy drinker. 18 around town and 22-24 highway on premium gas. Beyond these nuances the car is capable, comfortable, solid on the road and for the money drives better than most newer cars and has more cargo space than most SUVs.

  Great Car - 2004 Audi A6
  By AQBill - December 4 - 2:00 am

  This is my 2nd Audi and with one exception, its been my favorite. Did have to replace transmission "computer" chip outside of warranty and they dont come cheap. On the other hand the car has provided wonderful service, Its stylish, comfortable, quiet, reliable and gets exceptional milage - 22 to 24 in town and 30 to 32 on the road at 70 mph. I am, however, a geezer driver - as my children tell me - so I dont flog either the engine or brakes.

  Phenomenal Car - 2004 Audi A6
  By Audifan - September 17 - 2:00 am

  Bought the 04 S-line in Sept 09 with 55k miles on it. Mint condition for 15k. Could not be happier! added APR chip to get HP to 310 and it really makes a difference. Used to have 3 series BMW and this blows it away. Build quality is so much better. best vehicle ive ever driven in foul weather (snow, rain). Very safe feeling in all situations. One thing i learned is Dealers will kill you on repairs. got to find an indy tech. watch out for the cam adjuster seal leak DLR scam. they claim its $1200 in labor. only takes them 2 hrs! find an independent mechanic or get warranty. wonderful car. had not problems at 72k miles yet.

  Once you go QUATTRO you cant go back! - 2004 Audi A6
  By VGHOSTINE - March 7 - 11:30 pm

  This is the best piece of man made machine I have ever driven. I drove Infiniti G35s and Nissan 350Z and then had two hondas and one gm. Of all those cars, I can say this is in its own category and nothing comes to close to the performance and comfort and style and OH YOU HAVE A NICE CAR comments. MY next car will be an A8L but I will enjoy every bit of my A6. Every time I start the engine and hear the muffler noise (modified) I just cant wait to hit on the gas pedal and accelerate. The feel is way beyond anything I can ever own and AFFORD to own. 20k$

  Audi 3.0 FWD - 2004 Audi A6
  By Audi Owner - January 20 - 10:48 am

  I purchased my audi 3.0 FWD two years ago used (had 25K miles on it at the time). I was surprised with the average gas mileage(averaged 26.4 mpg) over the past two years. On the down side, I spent a lot of time in the shop for small items (some covered by warranty). Repairs included new battery, 4 cv boots, head light, two tail lights. On average I spent $1,200 per year in repairs not including oil changes, brakes and tires/rotations. Overall interior quality was less than I expected. The seats showed significant wear, the radio/heating buttons writing wore off and the wood (plastic) cracked during my two years of ownership. I previously owned a saab 9-5 and had none of these problems.

  Nice, Costly Family Sportster - 2004 Audi A6
  By Nice, Costly Car - August 26 - 7:46 am

  I bought this car from pampering owner. I had a 98 A8 10yrs ago that I prefer. The car looks awesome but I find myself nickel and diming my way through ownership of this Audi too. Both of my 5 series BMWs and my two Volvos (S60 & S80) were much less expensive to own. I hit a small deer at 20 mph that cost 5K to repair- chalk 1 for the dealer. Cant seem to get the ride completely smooth and the dealership always finds something. The car is not as fast off the line as the engine sounds, but it is great on the highway. Big gas tank is great for trips and the highway mpg is great--especially compared to the dismal in-city driving with a heavy foot. Overall- not sure its worth it.

  AMAZING - 2004 Audi A6
  By MHess81 - August 8 - 9:52 pm

  I just bought this car at the beginning of the week, but did a lot of reviews on it, and they were all very good. I LOVE the car so far. I cant wait until this winter to try out the AWD! I just wish the gas mileage was a bit better, but its ok for how amazing the car is!

  2004 model year has the best reliability - 2004 Audi A6
  By jimsrod - July 10 - 5:59 pm

  Im the 2nd owner off lease. Ive been driving it for 2 years now. First couple of months the car was stock and throttle response a bit dead. I had the ECU chipped and it really livened it up. Plus gas mileage is a couple per gallon better (not great about 20 MPG combined city / hwy). Ive tinted the windows and added aftermarket wheels to the otherwise boring design of the 18" S- Line stockers. Oil lines to the turbos were updated for 2004 so no more blown turbos (one goes youve got to replace the other)! Ride is very nice and not too harsh. S-Line A6 2.7ts arent on every corner so you feel like youre in a more exclusive club. Love the car...luxury and sportiness all in one!

  AUDIOS to BMW and Mercedes! - 2004 Audi A6
  By audios66 - May 20 - 10:18 pm

  Having owned 3 Audis this is by far the best one... quality, comfort, speed, all weather capable... what more is there! This Audi beats BMW and Mercedes... hands down... the only downfall is the HIGH maintenance costs. But every car is high to maintain these days.

  LUXURY & sport for 20k - 2004 Audi A6
  By Cory - May 1 - 5:05 pm

  If youre dumb enough to buy a $50k car and complain that it costs a lot to maintain (when you only paid 20k for it) then shame on you. This is a phenomenal car and beats the pants off any comparable, or even brand new, car you can get for ~20k. Ive had 2 and loved them both. (148k miles, and 22k miles) The car is fast, comfortable, reliable (if you keep it up), and an awesome daily driver.
