The 2007 Audi a6 (the a stands for awesome).
My car is an 2007 Audi a6 quattro. It gets about 21 city miles to the gallon and between 24 and 25 highway miles to the gallon. I love the way my car drives and handles in the snow- living in Wisconsin winters makes that a very important thing! It also is a very heavy car, mine is about 5000 lbs. It gets up to speed fast and it does not feel like you are going very fast.
