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.


Best 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.


Worst Features

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.

2004 Audi A6 2.7T quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)


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.


Best Features

Looks, performance, handling


Worst Features

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.


Best Features

Quality inside and out; big trunk; CVT; sound system; good road manners; good gas mileage; and, great overall design.


Worst Features

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.


Best Features

Interior styling, Bose stereo. Fold down rear seats. Full size spare.


Worst Features

Reliability, tighter bucket seats
