Cleanest design of all large sedans. Extreme comfort and adequate power. Purchased a used one off lease and saved 50% of sticker price. Not sure if it was very well cared for or the build quality is that exceptional, but the car is in nearly brand new condition after 36k miles.
After years of Mercedes ownership (and a brief BMW period) I finally got over to Audi. This car is everything that Mercedes used to be. Understatedly elegant, fantastically finished and user friendly. What a true pleasure to drive. In fact, what a pleasure to just sit in. Nobody does interiors like Audi. It is just beautiful, comfortable, and functional. We took delivery in Germany at Ingolstadt, which was a once in a lifetime experience, and did use it on the Autobahn. 130 mph is like 60 mph. wonderful road car! While I think Mercedes has lost their way, Audi seems to have really found their's. Some people are put off by the conservative styling of the exterior. I find it refreshing.
I've owned an LS430, E430 MB, and driven 5 and 7 series BMWs. This is by far and away the most refined yet sporty total package that I've ever driven. I'm always looking for reasons to take this care out on the road. It's suspension and handling are amazing, combining control with the smoothest most comfortable ride while avoiding the numb feeling that I used to experience with the Lexus. The whisper quiet interior (absolutely gorgeous in cognac brown) allows me to hear my iPod/CDs/Sirius through the B&O audiophile system. What an amazing aggregation of technology, craftsmanship, thoughtful design. Driven for one year - no problems yet.
The A8 is still the best value among large luxury sedans. I've owned BMWs and driven a colleague's S550 and the A8 is just superior everywhere it counts. I still can't believe how comfortable and fun this car is. I find myself looking for every excuse to go anywhere in this car on any errand. I opted for the L for extra leg room. Kids can't touch the back of my seat no matter how far they stretch. Important options are the acoustic glass which makes it quieter than the S550, ventilated seats, 19" wheels, and Lane/Side Assist because it actually helps. The ride is fantastic on rough New England roads and you never feel like you're rushed when you're in this car. Best car I have ever driven.
I love this A-8. After owning various Jaguars, Lexus (which was also terrific), Infinity Q-45, various BMW models and other luxury vehicles, the Audi A-8 is by far...the best. The interior is true luxury, the ride is exceptional, we love the Nav system which also operates most functions of the vehicle,and the stereo system is terrific. Exceptional fuel mileage too! When I am ready to trade in this vehicle I believe I will get another Audi.
