As much as the A7 is near-perfect, I think the A6 might even be better. The design is absolutely beautiful. The front overhang is the only imperfection to my eyes. The entire thing is so low-slung and taught. Very, very nice.
I'm really impressed by the weight. The 2.0T's EPA 25/33 is an impressive feat. I even like the way they equipped it. Lots of the advanced/luxury things you would expect from that class of car, and intelligent axing of some that are better served by the 3.0T or S6. Last time my car was in the shop, I fell in love with the A6 interior. The A4 pales.
The 2.0T engine would be ideal for me. I don't subscribe to this abundance of overwhelming power nonsense. Most of the driving I do is in the city to get to the highway, then cruising on the highway. 200hp is more than enough for all that.
What I don't like is the CVT.
