Solid performance and an elegant cabin design make the A6 a worthy competitor in the luxury sedan class, but BMW's 5 Series is more athletic and Mercedes carries more brand cachet, so it can't be called a class leader just yet.

Bought this off the lot with 62k miles on it. This will be my daily driver. Purchased for it's 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.

This is my 2nd Audi and with one exception, it's been my favorite. Did have to replace transmission "computer" chip outside of warranty and they don't come cheap. On the other hand the car has provided wonderful service, It's 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 don't flog either the engine or brakes.

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 i've 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.

This is the best piece of man made machine I have ever driven. I drove Infiniti G35's 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$

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.

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 BMW's and my two Volvo's (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. Can't 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 it's worth it.
