2004 Audi A6 2.7T S-Line quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)
Review
We were needing to get something a little larger than our A4. I looked at Caddys, Jags, Beemers, Mercs and Inf. There was always something about them that made them either feel very dated on the inside (Jag, Merc, BMW) or cheap on the inside (Inf, Caddy). When I first looked at the A6 I looked at the 3.0 CVT model, but heard many negs about the CVT. Decided to risk the turbos and step up to the 2.7T S-Line as it wasn't much more money on the used market. I am so pleased with my decision. The car is beautiful inside and out. It performs great in all conditions. Decent fuel economy. I haven't loved a car as much as this one since my 1993 & 97 Infiniti J30. And this car blows em away.
Favorite Features
Sport Leather Seats, Sport 18 inch wheels, red gauges and red mood light from ceiling, interior fit and finish. Hasn't dated at all despite it being a 5 year old car. Take a look at the BMW and it looks far older. Handles awesomely for such a heavy car!
Suggested Improvements
Turbo boost gauge should be in instrument cluster or onboard LCD screen. I would like to know when it is in operation as I try to warm the car up before I run it hard. Automatic headlights would be nice too.
Worth It

2004 Audi A6 3.0 quattro AWD 4dr Sedan (3.0L 6cyl 5A)
Review
Bought the car for my wife and we both love it. The ride is great, and the cabin is first class. When I walk by it I can't help but stare at it. Had one problem bad brake light switch caused alarms, but $100 fix. Now I'm looking for the A6 4.2 V8 for me. Mercedes are so bland and BMW's are ugly. If you want a great car that makes you happy every time you drive it, buy Audi.

2004 Audi A6 2.7T S-Line quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)
Review
This is a great car for any family. The added bonus (for dad or mom) is the easy modification. I have added a GIAC perfromance chip, cold air intake and better turbo valves. This car easily outruns a Mustang GT in the straight line and on the track. It is fun to pass so-called "sports cars" with my son's car-seat in the back.
Favorite Features
The dual turbo easily accepts upgrades. The performance chip added over 60 hp and 70 lbs/ft tq. for only $500. Cold air iontake added over over 10 hp.
Suggested Improvements
Gas mileage is low, and the rear seats should fold down. Luxury is defined by options. A large trunk should give way to folding seats.

Review
Have owned Volvos, Benz, Bimmers, you name it; our 2004 S-line A6 has been the best handling, most reliable auto ever. Chicago winters, no problem. Many x-country trips in every season. The car has never once let us down. Minor electronic nuisance with turn signal relay, but that's it. Developed outside water leak in front passenger floor area which we still haven't tracked down, but what the hey...shopping for a nice all road with the same mechanicals as we need more room to carry stuff with a new business. Highly recommend this vehicle to anyone in the market.
Favorite Features
Looks, performance, handling
Suggested Improvements
Cup holders, some minor plastic parts could be metal (arm rest hinge assembly)...brake light, turn signal relays need better quality

2004 Audi A6 3.0 Avant quattro AWD 4dr Wagon (3.0L 6cyl 5A)
Review
Vehicle started leaking oil and running rough at less than 12k. Dealer would not repair. Finaly after many complaints, dealer found coolant was leaking into the head gaskets. Short story is dealer has had the head gaskets out 3 separate times to 'resurface', car still leaking oil, repaired that several times. I was told the car is like a piece of cheese, when one hole is fixed, another opens up! That must be professional mechanic speak. Car has been in 29 times for serious repair in less than 2 years.

2004 Audi A6 3.0 Fwd 4dr Sedan (3.0L 6cyl CVT)
Review
Love the look and, so far, love the car. Purchased used with 8 months remaining on warranty which provided a little peace of mind. Nearest dealer is 70 miles away but so far that has not proven to be an issue. Previously owned a 1984 Audi 5000 with manual transmission that I loved but didn't care for the high cost of maintenance and repair. I put more than 240k miles on it before I traded. This newer one is substantially more sophisticated than the 1984 version and, I hope, more reliable. Have been amazed by in-town gas mileage which averages over 22 mpg in town to go with a respectable 30 mpg on the highway. I do drive conservatively and plan to keep the A6 for a long time.
Favorite Features
Quality inside and out; big trunk; CVT; sound system; good road manners; good gas mileage; and, great overall design.
Suggested Improvements
More - and larger - cup holders!

2004 Audi A6 2.7T S-Line quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)
Review
I have owned two Audi A6 2.7 S lines. The car handles great and has a sleek look. You can't beat the sophisticated interior and the features are extremely well thought out. However, if you intend to buy this car without an warranty or extended warranty beware! I have been to the shop too many times. I know all the technicians by name and could give you their family histories. Electronic problems, oil leakage, bad gaskets, transmission, transmission, transmission. Did I mention transmission. I love the car, but I'm going japanese from here. good luck.
Favorite Features
Interior styling, Bose stereo. Fold down rear seats. Full size spare.
Suggested Improvements
Reliability, tighter bucket seats

2004 Audi A6 2.7T quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)
Review
This car is the 29th registered in my name. Love the style, motor, and creature comforts. Great acceleration, comfortable on my frequest long drives. Seems to have a great build quality. Bought it certified, definitely the way to go. Black on black with S-line, cold weather, and all the creature comforts. I get stopped all the time by people commenting on it. Not bad considering the new body style in 05
Favorite Features
Engine! Seats, audio, 1 touch power windows, style, trunk space, xenons
Suggested Improvements
Window roll down feature from remote, stick shift, RNS-E (touch screen navi) A way to chip the car and not void the warranty!

Review
This is honestly the best car I have ever owned. I bought it with 45000 as a CPO and haven't looked back. No issues at all so far and I just keep loving it more and more as the days go on. You will not find a better all wheel drive system out there. This past winter was a breeze driving around, it literally feels like your on rails.
Favorite Features
Smooth twin turbo V6, bose sound system, quattro system, interior design.
Suggested Improvements
Cup holders - but who buys a car for the cup holders anyways.

Review
After owning an E55 AMG this Audi seems a bit slow by comparison. The ride quality is exceptional however the overall handling is not up to par with other "sports sedans". I am impressed with most of what this car has to offer. I am not a big fan of the "quattro" system however, living in No. California there really is no need for "AWD". I wish that Audi would offer their cars with "rear wheel drive" and quattro. This is a fine car for anyone seeking a high line luxury used car. I would recommend the Audi extended warranty with any used German car you consider purchasing. There is just too much that can go wrong with these highly technical vehicles.
Favorite Features
Interior design and materials. Bose sound system, sporty exterior design w/the S-Line package trim.
Suggested Improvements
Wish it got better gas mileage (averaging 19-21 overall) and would have preferred rear wheel drive to AWD.
