 I purchased the 2010 Audi A6 3.0 supercharged early this year.  WOW what a car.  I'm an Acura guy and looked hard at a RL, the ZDX, and another MDX (would have been my third)  All are great cars with only the MDX considerably less expensive.  They just didn't thrill me.  I was leasing my first company vehicle and I have owned/driven many of the premium brands.  I was always drawn to the Audi, I hardly see one on the road.  The ride is plush, the gadgets are over the top cool, and the 3.0 supercharged engine is top notch.  Its been in the shop once already for check engine (dirt in a sensor) but I don't care.  Every time I drive it I'm smiling ear to ear!
