My A6 continues to be plagued with problems. Spent 10 days in the shop over thanksgiving. Oil seals on all 6 cylinders had to be replaced. A major job on a car with only 12k miles. The carbon buildup issue which was initially attributed to a computer reprogram turned out to be failing seals. I also mentioned a rattle/squeak from the front left suspension; dealer greased the suspension per Audi directives but to no avail. Car was in the shop for 1 week. Now it turns out that it may be a bushing problem (a known issue amongst Audis) and I am being asked to take the car back again. BTW - JDPower only gives the A6 a 6 rating which is on the cusp of below average.
When its out of the shop and firing on all cylinders, the A6 is an exciting, enjoyable car to drive.
For a large car, the A6 handles very well. I come from a smaller sports car so driving the A6 took some getting used to. The steering is soft, but responsive. Starts are slow, but once she's up to speed, the power is awesome! Passing slower vehicles is not a problem. The interior is plush and comfortable and there's nothing better when driving at night with all the lights on. Having the controls on the console was awkward at first since it is difficult to change settings while driving. I don't suggest it! However, once set up, voice activation is the key to easy and safe operation. Although difficult to comprehend at first, once learned, the MMI and navigation system is a cinch to use.
The Bose stereo is awesome! I've never enjoyed listening to music in any car I've owned as much as I do in the A6. Having multiple screens for on- board information is great. It allows the driver to see the radio stations while having the navigation system displayed.
Improve torque for quicker starts. The sluggish start-off can be a problem when starting off from a full stop.

This is my fourth Audi, second A6. Best of them all! The power is great, smooth ride, unbeatable interior quality/design. I know that there are cars that are quicker, better handling, flashier, more powerful, etc, but no other car, taken as a package, does it all better than this A6. Can't beat quattro in the snow and rain. After 17K miles: NO PROBLEMS AT ALL, just changing the oil every 5K (not the factory recommended 10K).
V8 power, acceleration, interior design. Superb ride and interior quietness.
A little better fore/aft balance to improve handling.
Beautifully designed inside and out. Great drive. BOSE sound system is incredible. My A6 performed flawlessly the 1st year but then problems started. At 9k miles the # 5 cylinder coil had to be completely replaced. At 10k miles, carbon buildup caused the check engine light to come on again. The on-board computer had to be reprogrammed. In addition to all this, Audi's consume oil like no other car I've ever owned. I literally have to drive around with a quart of oil in my trunk because it needs to be constantly topped up. 5 times this year alone. Finally, the front suspension is starting to creak on rough roads and it's getting progressively louder. Disappointing for a car this new.
Bose sound system, MMI interface and IPOD connectivity.
Overall engine reliability and perhaps an attempt to design an engine that consumes less synthetic oil.

I'll agree with the editor's reviews that the low-end torque is an issue. She's just a bit slow off the starting line, but she shines once she's on the road. There's plenty of pedal when you need it, and I think she runs the best slightly above the recommended speed limit. I've owned Toyota's, BMW's and of course American cars. The Audi is my favorite to date. You won't be sorry, if you go this direction. I'm always getting compliments on this car, yet you don't feel too "cocky" driving it.
The MMI is awesome. Passing power on the highway is terrific. Highway mileage has been much better than expected. I had a 6 hour drive recently and was getting 31 MPG!!
Low-end torque. Ipod interface would be terrific as a standard option, if not the interface at least an aux jack!
