 My New Audi A6 quattro is the best car I have ever driven bar none!  The power of this car thrills me. The Tiptronic transmission is so smooth you can barely feel the shift. It accelerates like a motorcycle. Drive mode and Sport mote are the same.  The interior is huge! I am 6'2" and I can completely stretch my legs all the way out. I can pull the seat forward to allow back seat passengers and I am still driving comfortably.  The Premium Plus and all weather package came with this car. It has the full MMI which has a 10 Gig hard drive for uploading media. the navigation is a little cumbersome at first, but if you use it enough you begin to see just how intuitive it is. I love this car!
