2006 Audi A6 3.2 Avant quattro 4dr Wagon AWD (3.1L 6cyl 6A)
Purchased our wagon with the intent of making long trips (Seattle to Boston) in comfort. The car exceeded our expectations in all areas. 29.5 mpg at75mph all day long for a car this size is as good as it gets. Around town I get 22-23mpg. Car has plenty of power, corners well, ride is more involved than a Lexus. Since new I have had 1 rattle (fixed at the free 15k mile svc). No further problems. Tires still look as if they have another 20k mi on top of the 27k they have now. Anyone looking at a wagon or an SUV should consider an '06 Avant. Audi depreciation makes this a great buy for you; an incentive for me to keep mine for 10 years.
MMI interface and the Nav system which has never let me down. Long haul seat comfort, exceptional gas mileage for this size car.
