Faults:

Nothing while I have had it, have not had it long. It is an older car and has a large history file, appears to be well looked after. No mention of any particular problem, though there are some expensive general wear and tear bills with many parts replaced, but I am aware these are expensive cars to maintain.

General Comments:

Black A6 from 2006, very modern looking even today. The car responds like a rocket. Very fast. Luxurious, love this car.

It's a diesel, 3.0, but do not expect great economy (35 mpg at best) but worth it for the performance. My old 530d was the same, though slightly better on fuel. Either way these are not cheap cars to run, but you can buy them very cheap, mine was less than £4000. Much better than standard 2.0 cars though.

Bigger than an A4, but not quite an A8, these cars compete in the middling executive range. But close your eyes and honestly the car is very smooth cruising; passengers could mistake it for a Rolls Royce, everyone comments on what a nice car it is and are surprised when I tell them how old it is and how much I got it for.

I love it and plan to keep it a long time as a second car.

Faults:

Nothing serious.

Leather has worn very quickly for a car of this price, driver's seat has worn on the sides of the seat.

All well used buttons have had black worn off, and are showing white plastic underneath.

Sometimes the car starts a little rough and feels a bit weak until it’s revved.

Tyres do not last long.

Computer senses incorrectly that bulbs go out.

General Comments:

The 3.2 FSI engine is extremely quick, the responsiveness and power is fantastic. Whether it's from a stop or it's overtaking from 90kmh to 130kmh, it is always ready and impressive.

Comfort is not that impressive. The interior of the car feels a little sterile and a little too German (like Lufthansa). The seats are a little hard and not always that comfy on a long trip. Also sometimes the steering and acceleration is lurchy and not comfort oriented; maybe a control similar to BMW's Adaptive Transmission Control could sort this out (as I'm sure Audi has this too, maybe it needs tweaking).

Handling is very good, and it sticks to the road very well. Sometimes I do not enjoy the over controlled feeling of the Quattro, and prefer rear wheel drive in cornering, but overall in the wet, sometimes this security is nice and well engineered (not really a criticism).

The car looks great and an interesting look - it seems similar to the approach that the BMW 5 and 7 series followed in the early 2000's... but pulled off a lot better. I hope this car doesn’t date as quickly as the previous A6 (Gen C5) has. This is an S line A6, and personally I think it looks better than the more boring looking standard A6.

The MMI interface is easy to use, and works well.

I do not like the way the car beeps when it thinks bulbs are not working or when you go over the over speed, it's a very loud PING, it's not a nice beep, sometimes scares me. Sound system is very good, lack of easy iPod interface is a bit of a pain as I had to get an input installed at $400 NZD, but sounds great.

Fuel economy on long trips is good to okay for the engine size and the fact it has 6 gears. On a long trip, I can get around 8.8-9.5l/100km, but around town it can be around 13+l/100km. Considering how low the engine revs and how it has 6 forward gears, I wonder that the Quattro uses a bit more fuel, and it makes me wonder if this 4WD craze is actually worth it?

Service tends to be about $1200 each time I go to Audi, as this is the second service I have had to pay for (following the ones before as part of purchase deal), it's a bit pricey for the little work they actually do. I may take it to my mechanic I take my other cars to. BUT! I am impressed by its reliability, although nothing should really have gone wrong at kilometers this low.

All features in the car work tremendously well, they feel very well engineered. It is a true example of great engineering, but sometimes it misses that human and the road element.

Faults:

Electrically adjustable steering column failed at 3 weeks old.

The 2007 satellite navigation DVD has corrupted the Traffic Management Control system and Audi still have not got a fix after 6 months. It is only a minor irritant.

General Comments:

Beautifully built car and nice to look at.

The air suspension was definitely worth the extra money. The Comms Pack 2 with DVD sat nav is a huge disappointment at £2000 extra, but the only way to get fully functional hands free capability. (A Tom Tom does the same job better with full 7 digit post code entry for £300!) Also Audi really are well behind in their compatibility and phone cradles for modern mobile phones. With their flash upgrade facility, it shouldn't be that difficult.

Surefooted and agile, but the steering is a little wooly around the centreline, but I would say that after 9 Mercedes Benz; the last being a E320 CDI estate. MB no 8 and 9 were terribly unreliable, hence my defection to Audi (BMW don't do the 4wd estate in the UK, and BMW drivers have an unfortunate image here... the Audi is seen at the thinking professionals car)
