Excellence isn't cheap, but it's worth it

As I filled out the survey and came to the "value" section, it was hard to settle on a good answer. The A6 is an absolutely wonderful car, but it costs a lot too - especially if you opt for the V6 and some upgrades. In the end, you do get what you pay for, so I settled on four stars, as the car is not a bargain by any means as was my 1999 A4 and 2007 A6 (both Quattro's and V6's). Had I not owned the aforementioned vehicles, I would never have ponied up $55-60k for this or another upscale sedan. But eight years with each previous Audi was enough to keep me coming back for more, even if I did vow to never again buy another one if the rate of inflation stays on course as it did between 2007 and this one. Putting financial matters aside, let's talk about what makes it worth the price for me. Aside from how solid the car feels inside and out, top to bottom, and aside from the top-notch technological features, I flat-out love the way this car performs in every mode of driving. I run 50 miles per day on twisty backroads in the foothills of the Blue Ridge Mountains, and this car makes every mile a pleasant one. Whether I am in the mood for some spirited driving or just relaxed cruising, the smoothness and grace with which this automobile takes these roads is little short of astonishing. It is silly-quick, handles like a sports car, and in true Audi form does it smoothly as silk. I do not advise anyone pay for the "sport package", as this one handles as well or better than did the 2007 A6 WITH a sport pkg. Bottom line: Even tho the car is quite attractive and had luxury appointments and technology aplenty, it still manages to give the driver a superb driving experience, which to me is priority #1. My only complaint is that the German carmakers who had always prided themselves on providing drivers with the best road-feel on planet earth have all gone with the electronic steering which takes so much of that feel away from the driver. I guess we have to chalk that one up to "progress". Interior appointments, as all have stated, are excellent, and the superb paint and bodywork will probably outlast all the mechanical components. If there was one nicety I would put in the must-have list, it would be the Bose stereo system. An automobile this good does not deserve to have lousy audio. If you want a sedan that pampers you while also understanding you actively appreciate an excellent driving experience, look no further. It may not be cheap, but you absolutely do get what you pay for.

Phenomenal mid-size luxury car! All of the benefits of the old, large V8 engines that used to be in the luxury cars, without any drawbacks. Not only do I get smooth power basically anywhere in the powerband, but I get exceptional fuel economy if I am cruising on the highway. The supercharger allows for the immediacy in power, which is essential for drama-free passing on the highway, and it also allows for quiet, efficient cruising. With a light foot, I have had the car exceed 38 mpg, with normal highway cruising returning ~30 mpg. I mean seriously, it feels like a crime having both power and efficiency. Everything else is as expected: quiet, comfortable cabin with class-leading technology, layout and materials used. The screen is beautiful, with NVIDIA graphics allowing for beautiful map rendering, the Bose sound system is rich, and the MMI is fantastic once you get used to it. I am techy so it took me about 1 day to learn the system while driving around, but I feel as though almost everything makes sense in terms of layout and ergonomics. The ride is not as supple as some of ultra-luxury cars with air-suspension, but those cars are no fun to drive. This is the perfect compromise. I bought the car used with ~5k miles on the odometer, which not only took a few thousand off the price, but more importantly gave me the piece of mind of a 5 year 100,000 mile warranty! My only question is how much less power does the 2.0T have? Because for day-to-day commuting, you don't even get into the power in this car. Yes, it's nice to have the power to pass 98% of cars I see on the highway, but at the same time, 90% of my driving is done with efficiency in mind.

The TDI is awesome. It has great mileage, wonderful handling and is very easy to drive. I drove from northern Michigan to Des Moines IA and back in 36 hours earlier this week. 1290+ miles and I filled up two times and had 410 miles left when I got home. Even better, I didn't feel like ground beef after that much time in the car. Still the one, three years later. This car has been great. 5 years later and still piling on the miles. Great car! Like it so much I picked up a gas one for my wife. Perfect for an around town car. Great on trips too, but nothing matches the deisel.

For 48 months this car was exquisite. Since it is off of warranty we have had a report of a leaking motor mount then when it was 109 degrees outside it quit running in the middle of six lanes of traffic. Put the hood up and escorted my 70 year old wife, beautiful but still 70, along with our 8 year old great granddaughter to a shady tree next to where the A6 quit. For over a month my beautiful A6 has been sitting in Audi of Temecula waiting for a fuel pump. Almost $4,000 in repairs needed for a car I can't even drive since there are no parts in the US and will not be until 8-8. My love has cooled; six months I researched before purchasing this A6 Quattro, $72,000 that I thought was a 10 year investment, now I'm forced to decide whether to keep it or just cut my losses and sell it.

Diesel emissions issues have been fixed satisfactorily, with no noticeable decline in performance or mileage. Interior and exterior reflect high quality and look and feel almost like new after 75000 miles! Great for long distance travel. Prior to this vehicle, I never kept a car for more than 5 years. This car, however, has been completely trouble free and looks and feels very much like it did when new. Although I would love to have a new car, I cannot bring myself to sell the 2014 A-6 TDI. It is simply too good, and the difference between it and a 2019 A-6 is insignificant. In addition, there are no more new Audi diesel vehicles available in the US.
