 Purchased leave return. I loved the way it looked, made heads turn, the power, and fuel mileage.  Bought certified lease return because they come with a 100,000 mile warranty.  Made me feel safe.  The car started using a lot of oil. Audi refills for free. The car started using 1/2 every 1000 miles.  I was told normal. It still ran like scalded dag.  I finally complained enough at the dealership that they "marked" my engine and did an oil consumption test at 78,000 miles.  The engine was shot.  It needed new pistons and rings.  Worse news oil consumption is NOT covered by Audi's extended warranty.  I also learned the 2.0 turbo aluminum block does NOT have steel sleeves.  I wont even discuss the rotor issue, sun roof failure, oil separator failure......etc.
