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


Review

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.


Best Features

Power after perf. chip added. Build quality. safety, power, cup holder is better than BMW at least. For 15k this is best car on the road hands down


Worst Features

Stick shift! how can they not make this in a stick. what a crime. turbo lag could be better. stereo could be a bit improved ( i don't have the Bose though)

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


Review

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$


Best Features

Engine turbo power. 265 hp and crazy 280 lbs torque for its years is sick. Road handling. Leather comfort. Interior space.


Worst Features

Cup holders located inside the arm rest is really not a good idea. But again, like someone said before, who needs a cup holder when you drive a car like that.

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


Review

I'm the 2nd owner off lease. I've 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). I've 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 you've got to replace the other)! Ride is very nice and not too harsh. S-Line A6 2.7t's aren't on every corner so you feel like you're in a more exclusive club. Love the car...luxury and sportiness all in one!


Best Features

Interior is beautiful (typical Audi) better than BMW and Mercedes. Steering wheel controls, smooth flowing exterior, lower suspension and better handling with the sport package. AC/Heat is very quick in doing its job. Very roomy interior with plenty of space for four 6' tall men. Quick car!


Worst Features

CUP HOLDERS for the front passengers. Stereo could be have more power. Stock diverter valves don't hold boost for the turbos effectively.

Review

If you're 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. I've 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.


Best Features

the things not listed in your common report: simplicity of design, advanced functionality, aerodynamics, steering control, durability of interior, ease on eyes displays, automated stereo, nav, environmental controls...


Worst Features

dash display lights fad afteer ~45k miles (in every one I've seen)

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.


Best 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!


Worst Features

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.
